What does 500多个 mean? In the following sentence on this article:


  ＬＡ　ＬＩＳＴＥ国际美食排行榜于２０１５年由法国人首创，收录１６５个国家的１６０００个优秀美食地点，参考５００多个专业美食指南和民众在线点评，得分靠前的１０００家餐厅进入下一年度全球美食排行榜。


Pleco says the following on the entry for 多个 (the same as MDBG):


  
  many
  multiple
  multi-
  


However, all of them seem to make no sense. I feel it is either as many as or more than ~.

So which one is the correct? Or does 500多个 mean more than 500 (like 535) or as many as 500 (emphasize the number)?

Also, does the reverse expression exist (e.g. 多个500)?
N 多 个 = over N:
Pleco has a bunch of sample sentences:
