Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600746, here are decompositions:

5 + 31600741 = 31600746
13 + 31600733 = 31600746
29 + 31600717 = 31600746
43 + 31600703 = 31600746
53 + 31600693 = 31600746
83 + 31600663 = 31600746
127 + 31600619 = 31600746
197 + 31600549 = 31600746

Showing the first eight; more decompositions exist.
