Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628662, here are decompositions:

19 + 8628643 = 8628662
61 + 8628601 = 8628662
109 + 8628553 = 8628662
181 + 8628481 = 8628662
199 + 8628463 = 8628662
241 + 8628421 = 8628662
313 + 8628349 = 8628662
541 + 8628121 = 8628662

Showing the first eight; more decompositions exist.
