Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596600, here are decompositions:

17 + 31596583 = 31596600
29 + 31596571 = 31596600
47 + 31596553 = 31596600
59 + 31596541 = 31596600
89 + 31596511 = 31596600
103 + 31596497 = 31596600
127 + 31596473 = 31596600
163 + 31596437 = 31596600

Showing the first eight; more decompositions exist.
