Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596462, here are decompositions:

43 + 31596419 = 31596462
59 + 31596403 = 31596462
61 + 31596401 = 31596462
71 + 31596391 = 31596462
83 + 31596379 = 31596462
151 + 31596311 = 31596462
269 + 31596193 = 31596462
311 + 31596151 = 31596462

Showing the first eight; more decompositions exist.
