Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680520, here are decompositions:

7 + 8680513 = 8680520
19 + 8680501 = 8680520
103 + 8680417 = 8680520
151 + 8680369 = 8680520
193 + 8680327 = 8680520
223 + 8680297 = 8680520
271 + 8680249 = 8680520
307 + 8680213 = 8680520

Showing the first eight; more decompositions exist.
