Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495084, here are decompositions:

41 + 31495043 = 31495084
197 + 31494887 = 31495084
317 + 31494767 = 31495084
347 + 31494737 = 31495084
503 + 31494581 = 31495084
587 + 31494497 = 31495084
617 + 31494467 = 31495084
641 + 31494443 = 31495084

Showing the first eight; more decompositions exist.
