Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628020, here are decompositions:

3 + 8628017 = 8628020
13 + 8628007 = 8628020
43 + 8627977 = 8628020
67 + 8627953 = 8628020
73 + 8627947 = 8628020
109 + 8627911 = 8628020
127 + 8627893 = 8628020
211 + 8627809 = 8628020

Showing the first eight; more decompositions exist.
