Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600732, here are decompositions:

11 + 31600721 = 31600732
29 + 31600703 = 31600732
113 + 31600619 = 31600732
239 + 31600493 = 31600732
281 + 31600451 = 31600732
311 + 31600421 = 31600732
431 + 31600301 = 31600732
599 + 31600133 = 31600732

Showing the first eight; more decompositions exist.
