Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470344, here are decompositions:

7 + 31470337 = 31470344
127 + 31470217 = 31470344
151 + 31470193 = 31470344
193 + 31470151 = 31470344
271 + 31470073 = 31470344
277 + 31470067 = 31470344
307 + 31470037 = 31470344
331 + 31470013 = 31470344

Showing the first eight; more decompositions exist.
