Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464514, here are decompositions:

5 + 31464509 = 31464514
71 + 31464443 = 31464514
113 + 31464401 = 31464514
173 + 31464341 = 31464514
233 + 31464281 = 31464514
281 + 31464233 = 31464514
467 + 31464047 = 31464514
593 + 31463921 = 31464514

Showing the first eight; more decompositions exist.
