Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476912, here are decompositions:

31 + 31476881 = 31476912
41 + 31476871 = 31476912
59 + 31476853 = 31476912
83 + 31476829 = 31476912
113 + 31476799 = 31476912
179 + 31476733 = 31476912
281 + 31476631 = 31476912
461 + 31476451 = 31476912

Showing the first eight; more decompositions exist.
