Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622792, here are decompositions:

13 + 31622779 = 31622792
79 + 31622713 = 31622792
109 + 31622683 = 31622792
151 + 31622641 = 31622792
163 + 31622629 = 31622792
193 + 31622599 = 31622792
283 + 31622509 = 31622792
499 + 31622293 = 31622792

Showing the first eight; more decompositions exist.
