Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596456, here are decompositions:

19 + 31596437 = 31596456
37 + 31596419 = 31596456
43 + 31596413 = 31596456
53 + 31596403 = 31596456
139 + 31596317 = 31596456
149 + 31596307 = 31596456
163 + 31596293 = 31596456
263 + 31596193 = 31596456

Showing the first eight; more decompositions exist.
