Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628860, here are decompositions:

3 + 8628857 = 8628860
13 + 8628847 = 8628860
61 + 8628799 = 8628860
73 + 8628787 = 8628860
109 + 8628751 = 8628860
151 + 8628709 = 8628860
199 + 8628661 = 8628860
307 + 8628553 = 8628860

Showing the first eight; more decompositions exist.
