Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563504, here are decompositions:

13 + 31563491 = 31563504
41 + 31563463 = 31563504
53 + 31563451 = 31563504
61 + 31563443 = 31563504
73 + 31563431 = 31563504
101 + 31563403 = 31563504
103 + 31563401 = 31563504
113 + 31563391 = 31563504

Showing the first eight; more decompositions exist.
