Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563774, here are decompositions:

37 + 31563737 = 31563774
41 + 31563733 = 31563774
103 + 31563671 = 31563774
127 + 31563647 = 31563774
173 + 31563601 = 31563774
181 + 31563593 = 31563774
223 + 31563551 = 31563774
283 + 31563491 = 31563774

Showing the first eight; more decompositions exist.
