Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596656, here are decompositions:

19 + 31596637 = 31596656
43 + 31596613 = 31596656
73 + 31596583 = 31596656
103 + 31596553 = 31596656
277 + 31596379 = 31596656
349 + 31596307 = 31596656
463 + 31596193 = 31596656
607 + 31596049 = 31596656

Showing the first eight; more decompositions exist.
