Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495712, here are decompositions:

19 + 31495693 = 31495712
109 + 31495603 = 31495712
211 + 31495501 = 31495712
379 + 31495333 = 31495712
439 + 31495273 = 31495712
499 + 31495213 = 31495712
541 + 31495171 = 31495712
709 + 31495003 = 31495712

Showing the first eight; more decompositions exist.
