Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476240, here are decompositions:

53 + 31476187 = 31476240
71 + 31476169 = 31476240
83 + 31476157 = 31476240
97 + 31476143 = 31476240
127 + 31476113 = 31476240
167 + 31476073 = 31476240
181 + 31476059 = 31476240
223 + 31476017 = 31476240

Showing the first eight; more decompositions exist.
