Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463448, here are decompositions:

19 + 31463429 = 31463448
41 + 31463407 = 31463448
59 + 31463389 = 31463448
61 + 31463387 = 31463448
127 + 31463321 = 31463448
131 + 31463317 = 31463448
167 + 31463281 = 31463448
179 + 31463269 = 31463448

Showing the first eight; more decompositions exist.
