Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494262, here are decompositions:

5 + 31494257 = 31494262
83 + 31494179 = 31494262
101 + 31494161 = 31494262
179 + 31494083 = 31494262
263 + 31493999 = 31494262
311 + 31493951 = 31494262
353 + 31493909 = 31494262
479 + 31493783 = 31494262

Showing the first eight; more decompositions exist.
