Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495282, here are decompositions:

41 + 31495241 = 31495282
83 + 31495199 = 31495282
173 + 31495109 = 31495282
239 + 31495043 = 31495282
263 + 31495019 = 31495282
359 + 31494923 = 31495282
569 + 31494713 = 31495282
593 + 31494689 = 31495282

Showing the first eight; more decompositions exist.
