Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463420, here are decompositions:

13 + 31463407 = 31463420
31 + 31463389 = 31463420
67 + 31463353 = 31463420
103 + 31463317 = 31463420
139 + 31463281 = 31463420
151 + 31463269 = 31463420
193 + 31463227 = 31463420
223 + 31463197 = 31463420

Showing the first eight; more decompositions exist.
