Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560822, here are decompositions:

23 + 31560799 = 31560822
31 + 31560791 = 31560822
71 + 31560751 = 31560822
103 + 31560719 = 31560822
109 + 31560713 = 31560822
113 + 31560709 = 31560822
149 + 31560673 = 31560822
191 + 31560631 = 31560822

Showing the first eight; more decompositions exist.
