Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574512, here are decompositions:

5 + 31574507 = 31574512
23 + 31574489 = 31574512
59 + 31574453 = 31574512
83 + 31574429 = 31574512
149 + 31574363 = 31574512
251 + 31574261 = 31574512
311 + 31574201 = 31574512
419 + 31574093 = 31574512

Showing the first eight; more decompositions exist.
