Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622766, here are decompositions:

23 + 31622743 = 31622766
37 + 31622729 = 31622766
53 + 31622713 = 31622766
67 + 31622699 = 31622766
73 + 31622693 = 31622766
79 + 31622687 = 31622766
83 + 31622683 = 31622766
103 + 31622663 = 31622766

Showing the first eight; more decompositions exist.
