Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563344, here are decompositions:

61 + 31563283 = 31563344
67 + 31563277 = 31563344
151 + 31563193 = 31563344
157 + 31563187 = 31563344
181 + 31563163 = 31563344
271 + 31563073 = 31563344
313 + 31563031 = 31563344
331 + 31563013 = 31563344

Showing the first eight; more decompositions exist.
