Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463244, here are decompositions:

17 + 31463227 = 31463244
31 + 31463213 = 31463244
41 + 31463203 = 31463244
47 + 31463197 = 31463244
83 + 31463161 = 31463244
97 + 31463147 = 31463244
107 + 31463137 = 31463244
157 + 31463087 = 31463244

Showing the first eight; more decompositions exist.
