Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563546, here are decompositions:

19 + 31563527 = 31563546
83 + 31563463 = 31563546
103 + 31563443 = 31563546
197 + 31563349 = 31563546
199 + 31563347 = 31563546
263 + 31563283 = 31563546
269 + 31563277 = 31563546
277 + 31563269 = 31563546

Showing the first eight; more decompositions exist.
