Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680448, here are decompositions:

31 + 8680417 = 8680448
79 + 8680369 = 8680448
151 + 8680297 = 8680448
181 + 8680267 = 8680448
199 + 8680249 = 8680448
229 + 8680219 = 8680448
277 + 8680171 = 8680448
349 + 8680099 = 8680448

Showing the first eight; more decompositions exist.
