Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563426, here are decompositions:

23 + 31563403 = 31563426
67 + 31563359 = 31563426
79 + 31563347 = 31563426
149 + 31563277 = 31563426
157 + 31563269 = 31563426
173 + 31563253 = 31563426
233 + 31563193 = 31563426
239 + 31563187 = 31563426

Showing the first eight; more decompositions exist.
