Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600750, here are decompositions:

17 + 31600733 = 31600750
29 + 31600721 = 31600750
47 + 31600703 = 31600750
131 + 31600619 = 31600750
227 + 31600523 = 31600750
239 + 31600511 = 31600750
257 + 31600493 = 31600750
431 + 31600319 = 31600750

Showing the first eight; more decompositions exist.
