Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628620, here are decompositions:

19 + 8628601 = 8628620
67 + 8628553 = 8628620
73 + 8628547 = 8628620
127 + 8628493 = 8628620
139 + 8628481 = 8628620
157 + 8628463 = 8628620
199 + 8628421 = 8628620
271 + 8628349 = 8628620

Showing the first eight; more decompositions exist.
