Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563796, here are decompositions:

3 + 31563793 = 31563796
23 + 31563773 = 31563796
59 + 31563737 = 31563796
113 + 31563683 = 31563796
149 + 31563647 = 31563796
227 + 31563569 = 31563796
269 + 31563527 = 31563796
353 + 31563443 = 31563796

Showing the first eight; more decompositions exist.
