Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680638, here are decompositions:

7 + 8680631 = 8680638
19 + 8680619 = 8680638
37 + 8680601 = 8680638
79 + 8680559 = 8680638
137 + 8680501 = 8680638
157 + 8680481 = 8680638
167 + 8680471 = 8680638
199 + 8680439 = 8680638

Showing the first eight; more decompositions exist.
