Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600744, here are decompositions:

3 + 31600741 = 31600744
11 + 31600733 = 31600744
23 + 31600721 = 31600744
41 + 31600703 = 31600744
233 + 31600511 = 31600744
251 + 31600493 = 31600744
293 + 31600451 = 31600744
443 + 31600301 = 31600744

Showing the first eight; more decompositions exist.
