Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495962, here are decompositions:

13 + 31495949 = 31495962
41 + 31495921 = 31495962
83 + 31495879 = 31495962
103 + 31495859 = 31495962
229 + 31495733 = 31495962
233 + 31495729 = 31495962
269 + 31495693 = 31495962
271 + 31495691 = 31495962

Showing the first eight; more decompositions exist.
