Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470374, here are decompositions:

37 + 31470337 = 31470374
151 + 31470223 = 31470374
157 + 31470217 = 31470374
181 + 31470193 = 31470374
223 + 31470151 = 31470374
277 + 31470097 = 31470374
307 + 31470067 = 31470374
337 + 31470037 = 31470374

Showing the first eight; more decompositions exist.
