Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464818, here are decompositions:

31 + 31464787 = 31464818
37 + 31464781 = 31464818
61 + 31464757 = 31464818
109 + 31464709 = 31464818
199 + 31464619 = 31464818
241 + 31464577 = 31464818
271 + 31464547 = 31464818
337 + 31464481 = 31464818

Showing the first eight; more decompositions exist.
