Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476916, here are decompositions:

173 + 31476743 = 31476916
293 + 31476623 = 31476916
467 + 31476449 = 31476916
479 + 31476437 = 31476916
503 + 31476413 = 31476916
563 + 31476353 = 31476916
599 + 31476317 = 31476916
677 + 31476239 = 31476916

Showing the first eight; more decompositions exist.
