Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463158, here are decompositions:

11 + 31463147 = 31463158
59 + 31463099 = 31463158
71 + 31463087 = 31463158
179 + 31462979 = 31463158
227 + 31462931 = 31463158
257 + 31462901 = 31463158
269 + 31462889 = 31463158
281 + 31462877 = 31463158

Showing the first eight; more decompositions exist.
