Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563714, here are decompositions:

31 + 31563683 = 31563714
43 + 31563671 = 31563714
67 + 31563647 = 31563714
113 + 31563601 = 31563714
163 + 31563551 = 31563714
223 + 31563491 = 31563714
251 + 31563463 = 31563714
263 + 31563451 = 31563714

Showing the first eight; more decompositions exist.
