Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476858, here are decompositions:

5 + 31476853 = 31476858
11 + 31476847 = 31476858
29 + 31476829 = 31476858
37 + 31476821 = 31476858
59 + 31476799 = 31476858
131 + 31476727 = 31476858
167 + 31476691 = 31476858
227 + 31476631 = 31476858

Showing the first eight; more decompositions exist.
