Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465712, here are decompositions:

151 + 31465561 = 31465712
349 + 31465363 = 31465712
601 + 31465111 = 31465712
613 + 31465099 = 31465712
643 + 31465069 = 31465712
673 + 31465039 = 31465712
709 + 31465003 = 31465712
739 + 31464973 = 31465712

Showing the first eight; more decompositions exist.
