Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470350, here are decompositions:

13 + 31470337 = 31470350
127 + 31470223 = 31470350
151 + 31470199 = 31470350
157 + 31470193 = 31470350
199 + 31470151 = 31470350
277 + 31470073 = 31470350
283 + 31470067 = 31470350
313 + 31470037 = 31470350

Showing the first eight; more decompositions exist.
