Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622020, here are decompositions:

3 + 8622017 = 8622020
13 + 8622007 = 8622020
19 + 8622001 = 8622020
31 + 8621989 = 8622020
37 + 8621983 = 8622020
61 + 8621959 = 8622020
73 + 8621947 = 8622020
109 + 8621911 = 8622020

Showing the first eight; more decompositions exist.
