Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464908, here are decompositions:

127 + 31464781 = 31464908
151 + 31464757 = 31464908
199 + 31464709 = 31464908
331 + 31464577 = 31464908
337 + 31464571 = 31464908
457 + 31464451 = 31464908
487 + 31464421 = 31464908
499 + 31464409 = 31464908

Showing the first eight; more decompositions exist.
