Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628722, here are decompositions:

13 + 8628709 = 8628722
61 + 8628661 = 8628722
79 + 8628643 = 8628722
229 + 8628493 = 8628722
241 + 8628481 = 8628722
373 + 8628349 = 8628722
541 + 8628181 = 8628722
601 + 8628121 = 8628722

Showing the first eight; more decompositions exist.
