Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494414, here are decompositions:

13 + 31494401 = 31494414
67 + 31494347 = 31494414
113 + 31494301 = 31494414
151 + 31494263 = 31494414
157 + 31494257 = 31494414
167 + 31494247 = 31494414
173 + 31494241 = 31494414
257 + 31494157 = 31494414

Showing the first eight; more decompositions exist.
