Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464512, here are decompositions:

3 + 31464509 = 31464512
19 + 31464493 = 31464512
31 + 31464481 = 31464512
61 + 31464451 = 31464512
73 + 31464439 = 31464512
103 + 31464409 = 31464512
241 + 31464271 = 31464512
433 + 31464079 = 31464512

Showing the first eight; more decompositions exist.
