Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492414, here are decompositions:

11 + 31492403 = 31492414
137 + 31492277 = 31492414
251 + 31492163 = 31492414
257 + 31492157 = 31492414
347 + 31492067 = 31492414
353 + 31492061 = 31492414
383 + 31492031 = 31492414
431 + 31491983 = 31492414

Showing the first eight; more decompositions exist.
