Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463956, here are decompositions:

47 + 31463909 = 31463956
59 + 31463897 = 31463956
107 + 31463849 = 31463956
113 + 31463843 = 31463956
149 + 31463807 = 31463956
197 + 31463759 = 31463956
239 + 31463717 = 31463956
449 + 31463507 = 31463956

Showing the first eight; more decompositions exist.
