Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574614, here are decompositions:

83 + 31574531 = 31574614
107 + 31574507 = 31574614
251 + 31574363 = 31574614
311 + 31574303 = 31574614
317 + 31574297 = 31574614
353 + 31574261 = 31574614
521 + 31574093 = 31574614
593 + 31574021 = 31574614

Showing the first eight; more decompositions exist.
