Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622882, here are decompositions:

19 + 31622863 = 31622882
73 + 31622809 = 31622882
79 + 31622803 = 31622882
103 + 31622779 = 31622882
139 + 31622743 = 31622882
199 + 31622683 = 31622882
211 + 31622671 = 31622882
241 + 31622641 = 31622882

Showing the first eight; more decompositions exist.
