Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680650, here are decompositions:

19 + 8680631 = 8680650
31 + 8680619 = 8680650
37 + 8680613 = 8680650
67 + 8680583 = 8680650
107 + 8680543 = 8680650
137 + 8680513 = 8680650
149 + 8680501 = 8680650
179 + 8680471 = 8680650

Showing the first eight; more decompositions exist.
