Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596568, here are decompositions:

71 + 31596497 = 31596568
131 + 31596437 = 31596568
149 + 31596419 = 31596568
167 + 31596401 = 31596568
251 + 31596317 = 31596568
257 + 31596311 = 31596568
359 + 31596209 = 31596568
449 + 31596119 = 31596568

Showing the first eight; more decompositions exist.
