Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563502, here are decompositions:

11 + 31563491 = 31563502
59 + 31563443 = 31563502
71 + 31563431 = 31563502
101 + 31563401 = 31563502
233 + 31563269 = 31563502
281 + 31563221 = 31563502
293 + 31563209 = 31563502
353 + 31563149 = 31563502

Showing the first eight; more decompositions exist.
