Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563694, here are decompositions:

11 + 31563683 = 31563694
23 + 31563671 = 31563694
47 + 31563647 = 31563694
101 + 31563593 = 31563694
167 + 31563527 = 31563694
251 + 31563443 = 31563694
263 + 31563431 = 31563694
293 + 31563401 = 31563694

Showing the first eight; more decompositions exist.
