Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596448, here are decompositions:

11 + 31596437 = 31596448
29 + 31596419 = 31596448
47 + 31596401 = 31596448
131 + 31596317 = 31596448
137 + 31596311 = 31596448
239 + 31596209 = 31596448
419 + 31596029 = 31596448
479 + 31595969 = 31596448

Showing the first eight; more decompositions exist.
