Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463764, here are decompositions:

5 + 31463759 = 31463764
47 + 31463717 = 31463764
83 + 31463681 = 31463764
173 + 31463591 = 31463764
257 + 31463507 = 31463764
281 + 31463483 = 31463764
401 + 31463363 = 31463764
443 + 31463321 = 31463764

Showing the first eight; more decompositions exist.
