Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596426, here are decompositions:

7 + 31596419 = 31596426
13 + 31596413 = 31596426
23 + 31596403 = 31596426
47 + 31596379 = 31596426
109 + 31596317 = 31596426
233 + 31596193 = 31596426
263 + 31596163 = 31596426
283 + 31596143 = 31596426

Showing the first eight; more decompositions exist.
