Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622996, here are decompositions:

37 + 31622959 = 31622996
73 + 31622923 = 31622996
103 + 31622893 = 31622996
193 + 31622803 = 31622996
283 + 31622713 = 31622996
313 + 31622683 = 31622996
367 + 31622629 = 31622996
397 + 31622599 = 31622996

Showing the first eight; more decompositions exist.
