Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596550, here are decompositions:

53 + 31596497 = 31596550
113 + 31596437 = 31596550
131 + 31596419 = 31596550
137 + 31596413 = 31596550
149 + 31596401 = 31596550
233 + 31596317 = 31596550
239 + 31596311 = 31596550
257 + 31596293 = 31596550

Showing the first eight; more decompositions exist.
