Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467812, here are decompositions:

3 + 31467809 = 31467812
223 + 31467589 = 31467812
241 + 31467571 = 31467812
331 + 31467481 = 31467812
379 + 31467433 = 31467812
613 + 31467199 = 31467812
631 + 31467181 = 31467812
643 + 31467169 = 31467812

Showing the first eight; more decompositions exist.
