Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680688, here are decompositions:

19 + 8680669 = 8680688
271 + 8680417 = 8680688
421 + 8680267 = 8680688
439 + 8680249 = 8680688
487 + 8680201 = 8680688
661 + 8680027 = 8680688
1231 + 8679457 = 8680688
1291 + 8679397 = 8680688

Showing the first eight; more decompositions exist.
