Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463456, here are decompositions:

67 + 31463389 = 31463456
103 + 31463353 = 31463456
127 + 31463329 = 31463456
139 + 31463317 = 31463456
229 + 31463227 = 31463456
373 + 31463083 = 31463456
379 + 31463077 = 31463456
433 + 31463023 = 31463456

Showing the first eight; more decompositions exist.
