Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463226, here are decompositions:

13 + 31463213 = 31463226
23 + 31463203 = 31463226
29 + 31463197 = 31463226
59 + 31463167 = 31463226
79 + 31463147 = 31463226
89 + 31463137 = 31463226
103 + 31463123 = 31463226
127 + 31463099 = 31463226

Showing the first eight; more decompositions exist.
