Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680478, here are decompositions:

7 + 8680471 = 8680478
61 + 8680417 = 8680478
109 + 8680369 = 8680478
151 + 8680327 = 8680478
181 + 8680297 = 8680478
211 + 8680267 = 8680478
229 + 8680249 = 8680478
277 + 8680201 = 8680478

Showing the first eight; more decompositions exist.
