Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680516, here are decompositions:

3 + 8680513 = 8680516
107 + 8680409 = 8680516
137 + 8680379 = 8680516
179 + 8680337 = 8680516
239 + 8680277 = 8680516
359 + 8680157 = 8680516
443 + 8680073 = 8680516
479 + 8680037 = 8680516

Showing the first eight; more decompositions exist.
