Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476906, here are decompositions:

53 + 31476853 = 31476906
59 + 31476847 = 31476906
107 + 31476799 = 31476906
163 + 31476743 = 31476906
173 + 31476733 = 31476906
179 + 31476727 = 31476906
283 + 31476623 = 31476906
313 + 31476593 = 31476906

Showing the first eight; more decompositions exist.
