Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546516, here are decompositions:

47 + 31546469 = 31546516
59 + 31546457 = 31546516
167 + 31546349 = 31546516
179 + 31546337 = 31546516
233 + 31546283 = 31546516
317 + 31546199 = 31546516
503 + 31546013 = 31546516
509 + 31546007 = 31546516

Showing the first eight; more decompositions exist.
