Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600582, here are decompositions:

53 + 31600529 = 31600582
59 + 31600523 = 31600582
71 + 31600511 = 31600582
89 + 31600493 = 31600582
131 + 31600451 = 31600582
173 + 31600409 = 31600582
263 + 31600319 = 31600582
281 + 31600301 = 31600582

Showing the first eight; more decompositions exist.
