Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476864, here are decompositions:

11 + 31476853 = 31476864
17 + 31476847 = 31476864
43 + 31476821 = 31476864
131 + 31476733 = 31476864
137 + 31476727 = 31476864
173 + 31476691 = 31476864
233 + 31476631 = 31476864
241 + 31476623 = 31476864

Showing the first eight; more decompositions exist.
