Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622822, here are decompositions:

13 + 31622809 = 31622822
19 + 31622803 = 31622822
43 + 31622779 = 31622822
79 + 31622743 = 31622822
109 + 31622713 = 31622822
139 + 31622683 = 31622822
151 + 31622671 = 31622822
181 + 31622641 = 31622822

Showing the first eight; more decompositions exist.
