Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596630, here are decompositions:

17 + 31596613 = 31596630
19 + 31596611 = 31596630
47 + 31596583 = 31596630
59 + 31596571 = 31596630
89 + 31596541 = 31596630
157 + 31596473 = 31596630
193 + 31596437 = 31596630
211 + 31596419 = 31596630

Showing the first eight; more decompositions exist.
