Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467512, here are decompositions:

3 + 31467509 = 31467512
31 + 31467481 = 31467512
79 + 31467433 = 31467512
211 + 31467301 = 31467512
283 + 31467229 = 31467512
313 + 31467199 = 31467512
331 + 31467181 = 31467512
379 + 31467133 = 31467512

Showing the first eight; more decompositions exist.
