Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628782, here are decompositions:

3 + 8628779 = 8628782
31 + 8628751 = 8628782
73 + 8628709 = 8628782
139 + 8628643 = 8628782
181 + 8628601 = 8628782
229 + 8628553 = 8628782
433 + 8628349 = 8628782
601 + 8628181 = 8628782

Showing the first eight; more decompositions exist.
