Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563496, here are decompositions:

5 + 31563491 = 31563496
53 + 31563443 = 31563496
137 + 31563359 = 31563496
149 + 31563347 = 31563496
227 + 31563269 = 31563496
347 + 31563149 = 31563496
359 + 31563137 = 31563496
467 + 31563029 = 31563496

Showing the first eight; more decompositions exist.
