Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563702, here are decompositions:

19 + 31563683 = 31563702
31 + 31563671 = 31563702
101 + 31563601 = 31563702
109 + 31563593 = 31563702
151 + 31563551 = 31563702
211 + 31563491 = 31563702
239 + 31563463 = 31563702
251 + 31563451 = 31563702

Showing the first eight; more decompositions exist.
