Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450376, here are decompositions:

7 + 31450369 = 31450376
157 + 31450219 = 31450376
277 + 31450099 = 31450376
283 + 31450093 = 31450376
409 + 31449967 = 31450376
439 + 31449937 = 31450376
523 + 31449853 = 31450376
619 + 31449757 = 31450376

Showing the first eight; more decompositions exist.
