Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495652, here are decompositions:

61 + 31495591 = 31495652
151 + 31495501 = 31495652
229 + 31495423 = 31495652
379 + 31495273 = 31495652
439 + 31495213 = 31495652
499 + 31495153 = 31495652
673 + 31494979 = 31495652
709 + 31494943 = 31495652

Showing the first eight; more decompositions exist.
