Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463364, here are decompositions:

11 + 31463353 = 31463364
43 + 31463321 = 31463364
47 + 31463317 = 31463364
83 + 31463281 = 31463364
103 + 31463261 = 31463364
137 + 31463227 = 31463364
151 + 31463213 = 31463364
167 + 31463197 = 31463364

Showing the first eight; more decompositions exist.
