Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476380, here are decompositions:

7 + 31476373 = 31476380
31 + 31476349 = 31476380
37 + 31476343 = 31476380
97 + 31476283 = 31476380
193 + 31476187 = 31476380
211 + 31476169 = 31476380
223 + 31476157 = 31476380
283 + 31476097 = 31476380

Showing the first eight; more decompositions exist.
