Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541482, here are decompositions:

53 + 31541429 = 31541482
83 + 31541399 = 31541482
239 + 31541243 = 31541482
353 + 31541129 = 31541482
431 + 31541051 = 31541482
443 + 31541039 = 31541482
461 + 31541021 = 31541482
491 + 31540991 = 31541482

Showing the first eight; more decompositions exist.
