Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563484, here are decompositions:

41 + 31563443 = 31563484
53 + 31563431 = 31563484
83 + 31563401 = 31563484
107 + 31563377 = 31563484
137 + 31563347 = 31563484
263 + 31563221 = 31563484
347 + 31563137 = 31563484
353 + 31563131 = 31563484

Showing the first eight; more decompositions exist.
