Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563366, here are decompositions:

7 + 31563359 = 31563366
17 + 31563349 = 31563366
19 + 31563347 = 31563366
83 + 31563283 = 31563366
89 + 31563277 = 31563366
97 + 31563269 = 31563366
113 + 31563253 = 31563366
157 + 31563209 = 31563366

Showing the first eight; more decompositions exist.
