Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628974, here are decompositions:

7 + 8628967 = 8628974
37 + 8628937 = 8628974
61 + 8628913 = 8628974
127 + 8628847 = 8628974
163 + 8628811 = 8628974
223 + 8628751 = 8628974
313 + 8628661 = 8628974
331 + 8628643 = 8628974

Showing the first eight; more decompositions exist.
