Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563416, here are decompositions:

13 + 31563403 = 31563416
67 + 31563349 = 31563416
139 + 31563277 = 31563416
163 + 31563253 = 31563416
223 + 31563193 = 31563416
229 + 31563187 = 31563416
373 + 31563043 = 31563416
433 + 31562983 = 31563416

Showing the first eight; more decompositions exist.
