Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563326, here are decompositions:

43 + 31563283 = 31563326
73 + 31563253 = 31563326
139 + 31563187 = 31563326
163 + 31563163 = 31563326
199 + 31563127 = 31563326
283 + 31563043 = 31563326
313 + 31563013 = 31563326
367 + 31562959 = 31563326

Showing the first eight; more decompositions exist.
