Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461046, here are decompositions:

167 + 31460879 = 31461046
173 + 31460873 = 31461046
263 + 31460783 = 31461046
317 + 31460729 = 31461046
389 + 31460657 = 31461046
509 + 31460537 = 31461046
563 + 31460483 = 31461046
647 + 31460399 = 31461046

Showing the first eight; more decompositions exist.
