Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628944, here are decompositions:

7 + 8628937 = 8628944
31 + 8628913 = 8628944
61 + 8628883 = 8628944
97 + 8628847 = 8628944
157 + 8628787 = 8628944
193 + 8628751 = 8628944
283 + 8628661 = 8628944
397 + 8628547 = 8628944

Showing the first eight; more decompositions exist.
