Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596822, here are decompositions:

29 + 31596793 = 31596822
53 + 31596769 = 31596822
71 + 31596751 = 31596822
73 + 31596749 = 31596822
79 + 31596743 = 31596822
109 + 31596713 = 31596822
113 + 31596709 = 31596822
149 + 31596673 = 31596822

Showing the first eight; more decompositions exist.
