Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463146, here are decompositions:

23 + 31463123 = 31463146
47 + 31463099 = 31463146
59 + 31463087 = 31463146
83 + 31463063 = 31463146
167 + 31462979 = 31463146
257 + 31462889 = 31463146
269 + 31462877 = 31463146
353 + 31462793 = 31463146

Showing the first eight; more decompositions exist.
