Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450350, here are decompositions:

37 + 31450313 = 31450350
59 + 31450291 = 31450350
79 + 31450271 = 31450350
103 + 31450247 = 31450350
131 + 31450219 = 31450350
233 + 31450117 = 31450350
251 + 31450099 = 31450350
257 + 31450093 = 31450350

Showing the first eight; more decompositions exist.
