Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628788, here are decompositions:

37 + 8628751 = 8628788
61 + 8628727 = 8628788
79 + 8628709 = 8628788
127 + 8628661 = 8628788
241 + 8628547 = 8628788
307 + 8628481 = 8628788
367 + 8628421 = 8628788
439 + 8628349 = 8628788

Showing the first eight; more decompositions exist.
