Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628810, here are decompositions:

11 + 8628799 = 8628810
19 + 8628791 = 8628810
23 + 8628787 = 8628810
31 + 8628779 = 8628810
37 + 8628773 = 8628810
59 + 8628751 = 8628810
83 + 8628727 = 8628810
101 + 8628709 = 8628810

Showing the first eight; more decompositions exist.
