Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622036, here are decompositions:

73 + 31621963 = 31622036
79 + 31621957 = 31622036
139 + 31621897 = 31622036
157 + 31621879 = 31622036
283 + 31621753 = 31622036
367 + 31621669 = 31622036
619 + 31621417 = 31622036
643 + 31621393 = 31622036

Showing the first eight; more decompositions exist.
