Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464698, here are decompositions:

79 + 31464619 = 31464698
127 + 31464571 = 31464698
151 + 31464547 = 31464698
271 + 31464427 = 31464698
277 + 31464421 = 31464698
619 + 31464079 = 31464698
631 + 31464067 = 31464698
739 + 31463959 = 31464698

Showing the first eight; more decompositions exist.
