Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596626, here are decompositions:

13 + 31596613 = 31596626
43 + 31596583 = 31596626
73 + 31596553 = 31596626
223 + 31596403 = 31596626
433 + 31596193 = 31596626
463 + 31596163 = 31596626
499 + 31596127 = 31596626
577 + 31596049 = 31596626

Showing the first eight; more decompositions exist.
