Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495682, here are decompositions:

19 + 31495663 = 31495682
79 + 31495603 = 31495682
181 + 31495501 = 31495682
331 + 31495351 = 31495682
349 + 31495333 = 31495682
409 + 31495273 = 31495682
619 + 31495063 = 31495682
733 + 31494949 = 31495682

Showing the first eight; more decompositions exist.
