Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622762, here are decompositions:

19 + 31622743 = 31622762
79 + 31622683 = 31622762
163 + 31622599 = 31622762
271 + 31622491 = 31622762
373 + 31622389 = 31622762
631 + 31622131 = 31622762
643 + 31622119 = 31622762
883 + 31621879 = 31622762

Showing the first eight; more decompositions exist.
