Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476270, here are decompositions:

19 + 31476251 = 31476270
31 + 31476239 = 31476270
83 + 31476187 = 31476270
101 + 31476169 = 31476270
113 + 31476157 = 31476270
127 + 31476143 = 31476270
151 + 31476119 = 31476270
157 + 31476113 = 31476270

Showing the first eight; more decompositions exist.
