Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622846, here are decompositions:

37 + 31622809 = 31622846
43 + 31622803 = 31622846
67 + 31622779 = 31622846
103 + 31622743 = 31622846
163 + 31622683 = 31622846
337 + 31622509 = 31622846
373 + 31622473 = 31622846
379 + 31622467 = 31622846

Showing the first eight; more decompositions exist.
