Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622796, here are decompositions:

17 + 31622779 = 31622796
19 + 31622777 = 31622796
53 + 31622743 = 31622796
67 + 31622729 = 31622796
83 + 31622713 = 31622796
97 + 31622699 = 31622796
103 + 31622693 = 31622796
109 + 31622687 = 31622796

Showing the first eight; more decompositions exist.
