Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530822, here are decompositions:

23 + 31530799 = 31530822
109 + 31530713 = 31530822
139 + 31530683 = 31530822
163 + 31530659 = 31530822
173 + 31530649 = 31530822
179 + 31530643 = 31530822
181 + 31530641 = 31530822
229 + 31530593 = 31530822

Showing the first eight; more decompositions exist.
