Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476966, here are decompositions:

7 + 31476959 = 31476966
19 + 31476947 = 31476966
113 + 31476853 = 31476966
137 + 31476829 = 31476966
167 + 31476799 = 31476966
223 + 31476743 = 31476966
233 + 31476733 = 31476966
239 + 31476727 = 31476966

Showing the first eight; more decompositions exist.
