Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680648, here are decompositions:

17 + 8680631 = 8680648
29 + 8680619 = 8680648
47 + 8680601 = 8680648
89 + 8680559 = 8680648
167 + 8680481 = 8680648
239 + 8680409 = 8680648
257 + 8680391 = 8680648
269 + 8680379 = 8680648

Showing the first eight; more decompositions exist.
