Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492330, here are decompositions:

11 + 31492319 = 31492330
53 + 31492277 = 31492330
71 + 31492259 = 31492330
167 + 31492163 = 31492330
173 + 31492157 = 31492330
239 + 31492091 = 31492330
251 + 31492079 = 31492330
257 + 31492073 = 31492330

Showing the first eight; more decompositions exist.
