Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680738, here are decompositions:

5 + 8680733 = 8680738
41 + 8680697 = 8680738
47 + 8680691 = 8680738
107 + 8680631 = 8680738
137 + 8680601 = 8680738
179 + 8680559 = 8680738
257 + 8680481 = 8680738
347 + 8680391 = 8680738

Showing the first eight; more decompositions exist.
