Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563814, here are decompositions:

41 + 31563773 = 31563814
131 + 31563683 = 31563814
167 + 31563647 = 31563814
263 + 31563551 = 31563814
383 + 31563431 = 31563814
467 + 31563347 = 31563814
593 + 31563221 = 31563814
677 + 31563137 = 31563814

Showing the first eight; more decompositions exist.
