Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563826, here are decompositions:

53 + 31563773 = 31563826
89 + 31563737 = 31563826
179 + 31563647 = 31563826
233 + 31563593 = 31563826
257 + 31563569 = 31563826
383 + 31563443 = 31563826
449 + 31563377 = 31563826
467 + 31563359 = 31563826

Showing the first eight; more decompositions exist.
