Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463508, here are decompositions:

19 + 31463489 = 31463508
31 + 31463477 = 31463508
79 + 31463429 = 31463508
101 + 31463407 = 31463508
179 + 31463329 = 31463508
191 + 31463317 = 31463508
227 + 31463281 = 31463508
239 + 31463269 = 31463508

Showing the first eight; more decompositions exist.
