Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467564, here are decompositions:

5 + 31467559 = 31467564
13 + 31467551 = 31467564
31 + 31467533 = 31467564
61 + 31467503 = 31467564
67 + 31467497 = 31467564
83 + 31467481 = 31467564
97 + 31467467 = 31467564
127 + 31467437 = 31467564

Showing the first eight; more decompositions exist.
