Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563482, here are decompositions:

19 + 31563463 = 31563482
31 + 31563451 = 31563482
79 + 31563403 = 31563482
199 + 31563283 = 31563482
229 + 31563253 = 31563482
409 + 31563073 = 31563482
439 + 31563043 = 31563482
499 + 31562983 = 31563482

Showing the first eight; more decompositions exist.
