Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463770, here are decompositions:

3 + 31463767 = 31463770
11 + 31463759 = 31463770
53 + 31463717 = 31463770
89 + 31463681 = 31463770
179 + 31463591 = 31463770
251 + 31463519 = 31463770
263 + 31463507 = 31463770
281 + 31463489 = 31463770

Showing the first eight; more decompositions exist.
