Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476984, here are decompositions:

37 + 31476947 = 31476984
53 + 31476931 = 31476984
67 + 31476917 = 31476984
103 + 31476881 = 31476984
113 + 31476871 = 31476984
131 + 31476853 = 31476984
137 + 31476847 = 31476984
163 + 31476821 = 31476984

Showing the first eight; more decompositions exist.
