Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600540, here are decompositions:

11 + 31600529 = 31600540
17 + 31600523 = 31600540
29 + 31600511 = 31600540
47 + 31600493 = 31600540
89 + 31600451 = 31600540
131 + 31600409 = 31600540
233 + 31600307 = 31600540
239 + 31600301 = 31600540

Showing the first eight; more decompositions exist.
