Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463044, here are decompositions:

113 + 31462931 = 31463044
167 + 31462877 = 31463044
233 + 31462811 = 31463044
251 + 31462793 = 31463044
293 + 31462751 = 31463044
461 + 31462583 = 31463044
467 + 31462577 = 31463044
491 + 31462553 = 31463044

Showing the first eight; more decompositions exist.
