Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563822, here are decompositions:

5 + 31563817 = 31563822
29 + 31563793 = 31563822
89 + 31563733 = 31563822
139 + 31563683 = 31563822
151 + 31563671 = 31563822
229 + 31563593 = 31563822
271 + 31563551 = 31563822
331 + 31563491 = 31563822

Showing the first eight; more decompositions exist.
