Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494914, here are decompositions:

7 + 31494907 = 31494914
97 + 31494817 = 31494914
151 + 31494763 = 31494914
193 + 31494721 = 31494914
223 + 31494691 = 31494914
271 + 31494643 = 31494914
277 + 31494637 = 31494914
331 + 31494583 = 31494914

Showing the first eight; more decompositions exist.
