Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549282, here are decompositions:

5 + 31549277 = 31549282
41 + 31549241 = 31549282
101 + 31549181 = 31549282
239 + 31549043 = 31549282
263 + 31549019 = 31549282
641 + 31548641 = 31549282
719 + 31548563 = 31549282
761 + 31548521 = 31549282

Showing the first eight; more decompositions exist.
