Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563604, here are decompositions:

3 + 31563601 = 31563604
11 + 31563593 = 31563604
53 + 31563551 = 31563604
113 + 31563491 = 31563604
173 + 31563431 = 31563604
227 + 31563377 = 31563604
257 + 31563347 = 31563604
383 + 31563221 = 31563604

Showing the first eight; more decompositions exist.
