Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628626, here are decompositions:

3 + 8628623 = 8628626
73 + 8628553 = 8628626
79 + 8628547 = 8628626
163 + 8628463 = 8628626
277 + 8628349 = 8628626
439 + 8628187 = 8628626
577 + 8628049 = 8628626
607 + 8628019 = 8628626

Showing the first eight; more decompositions exist.
