Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467664, here are decompositions:

17 + 31467647 = 31467664
71 + 31467593 = 31467664
113 + 31467551 = 31467664
131 + 31467533 = 31467664
167 + 31467497 = 31467664
197 + 31467467 = 31467664
227 + 31467437 = 31467664
233 + 31467431 = 31467664

Showing the first eight; more decompositions exist.
