Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539822, here are decompositions:

5 + 31539817 = 31539822
59 + 31539763 = 31539822
109 + 31539713 = 31539822
151 + 31539671 = 31539822
163 + 31539659 = 31539822
173 + 31539649 = 31539822
179 + 31539643 = 31539822
229 + 31539593 = 31539822

Showing the first eight; more decompositions exist.
