Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680818, here are decompositions:

5 + 8680813 = 8680818
7 + 8680811 = 8680818
17 + 8680801 = 8680818
37 + 8680781 = 8680818
101 + 8680717 = 8680818
127 + 8680691 = 8680818
149 + 8680669 = 8680818
199 + 8680619 = 8680818

Showing the first eight; more decompositions exist.
