Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596416, here are decompositions:

3 + 31596413 = 31596416
13 + 31596403 = 31596416
37 + 31596379 = 31596416
109 + 31596307 = 31596416
223 + 31596193 = 31596416
349 + 31596067 = 31596416
367 + 31596049 = 31596416
409 + 31596007 = 31596416

Showing the first eight; more decompositions exist.
