Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465124, here are decompositions:

13 + 31465111 = 31465124
151 + 31464973 = 31465124
157 + 31464967 = 31465124
241 + 31464883 = 31465124
337 + 31464787 = 31465124
367 + 31464757 = 31465124
547 + 31464577 = 31465124
577 + 31464547 = 31465124

Showing the first eight; more decompositions exist.
