Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463154, here are decompositions:

7 + 31463147 = 31463154
17 + 31463137 = 31463154
31 + 31463123 = 31463154
67 + 31463087 = 31463154
71 + 31463083 = 31463154
131 + 31463023 = 31463154
223 + 31462931 = 31463154
257 + 31462897 = 31463154

Showing the first eight; more decompositions exist.
