Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563544, here are decompositions:

17 + 31563527 = 31563544
53 + 31563491 = 31563544
101 + 31563443 = 31563544
113 + 31563431 = 31563544
167 + 31563377 = 31563544
197 + 31563347 = 31563544
503 + 31563041 = 31563544
557 + 31562987 = 31563544

Showing the first eight; more decompositions exist.
