Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556282, here are decompositions:

3 + 31556279 = 31556282
139 + 31556143 = 31556282
271 + 31556011 = 31556282
283 + 31555999 = 31556282
313 + 31555969 = 31556282
349 + 31555933 = 31556282
409 + 31555873 = 31556282
619 + 31555663 = 31556282

Showing the first eight; more decompositions exist.
