Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464816, here are decompositions:

7 + 31464809 = 31464816
29 + 31464787 = 31464816
59 + 31464757 = 31464816
107 + 31464709 = 31464816
167 + 31464649 = 31464816
197 + 31464619 = 31464816
199 + 31464617 = 31464816
239 + 31464577 = 31464816

Showing the first eight; more decompositions exist.
