Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596644, here are decompositions:

7 + 31596637 = 31596644
31 + 31596613 = 31596644
61 + 31596583 = 31596644
73 + 31596571 = 31596644
103 + 31596541 = 31596644
241 + 31596403 = 31596644
337 + 31596307 = 31596644
523 + 31596121 = 31596644

Showing the first eight; more decompositions exist.
