Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546678, here are decompositions:

17 + 31546661 = 31546678
41 + 31546637 = 31546678
227 + 31546451 = 31546678
257 + 31546421 = 31546678
461 + 31546217 = 31546678
479 + 31546199 = 31546678
491 + 31546187 = 31546678
659 + 31546019 = 31546678

Showing the first eight; more decompositions exist.
