Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680722, here are decompositions:

5 + 8680717 = 8680722
23 + 8680699 = 8680722
31 + 8680691 = 8680722
53 + 8680669 = 8680722
103 + 8680619 = 8680722
109 + 8680613 = 8680722
139 + 8680583 = 8680722
163 + 8680559 = 8680722

Showing the first eight; more decompositions exist.
