Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456294, here are decompositions:

3 + 31456291 = 31456294
17 + 31456277 = 31456294
47 + 31456247 = 31456294
53 + 31456241 = 31456294
101 + 31456193 = 31456294
131 + 31456163 = 31456294
173 + 31456121 = 31456294
227 + 31456067 = 31456294

Showing the first eight; more decompositions exist.
