Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680782, here are decompositions:

13 + 8680769 = 8680782
29 + 8680753 = 8680782
41 + 8680741 = 8680782
59 + 8680723 = 8680782
83 + 8680699 = 8680782
113 + 8680669 = 8680782
151 + 8680631 = 8680782
163 + 8680619 = 8680782

Showing the first eight; more decompositions exist.
