Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493410, here are decompositions:

71 + 31493339 = 31493410
89 + 31493321 = 31493410
239 + 31493171 = 31493410
257 + 31493153 = 31493410
353 + 31493057 = 31493410
401 + 31493009 = 31493410
419 + 31492991 = 31493410
467 + 31492943 = 31493410

Showing the first eight; more decompositions exist.
