Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476366, here are decompositions:

13 + 31476353 = 31476366
17 + 31476349 = 31476366
23 + 31476343 = 31476366
83 + 31476283 = 31476366
127 + 31476239 = 31476366
179 + 31476187 = 31476366
197 + 31476169 = 31476366
223 + 31476143 = 31476366

Showing the first eight; more decompositions exist.
