Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464812, here are decompositions:

3 + 31464809 = 31464812
31 + 31464781 = 31464812
103 + 31464709 = 31464812
163 + 31464649 = 31464812
193 + 31464619 = 31464812
241 + 31464571 = 31464812
331 + 31464481 = 31464812
349 + 31464463 = 31464812

Showing the first eight; more decompositions exist.
