Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463340, here are decompositions:

11 + 31463329 = 31463340
19 + 31463321 = 31463340
23 + 31463317 = 31463340
59 + 31463281 = 31463340
71 + 31463269 = 31463340
79 + 31463261 = 31463340
113 + 31463227 = 31463340
127 + 31463213 = 31463340

Showing the first eight; more decompositions exist.
