Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563676, here are decompositions:

5 + 31563671 = 31563676
29 + 31563647 = 31563676
83 + 31563593 = 31563676
107 + 31563569 = 31563676
149 + 31563527 = 31563676
233 + 31563443 = 31563676
317 + 31563359 = 31563676
467 + 31563209 = 31563676

Showing the first eight; more decompositions exist.
