Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613170, here are decompositions:

53 + 31613117 = 31613170
179 + 31612991 = 31613170
257 + 31612913 = 31613170
317 + 31612853 = 31613170
431 + 31612739 = 31613170
443 + 31612727 = 31613170
503 + 31612667 = 31613170
509 + 31612661 = 31613170

Showing the first eight; more decompositions exist.
