Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600752, here are decompositions:

11 + 31600741 = 31600752
19 + 31600733 = 31600752
31 + 31600721 = 31600752
59 + 31600693 = 31600752
83 + 31600669 = 31600752
89 + 31600663 = 31600752
223 + 31600529 = 31600752
229 + 31600523 = 31600752

Showing the first eight; more decompositions exist.
