Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680490, here are decompositions:

19 + 8680471 = 8680490
73 + 8680417 = 8680490
163 + 8680327 = 8680490
193 + 8680297 = 8680490
223 + 8680267 = 8680490
241 + 8680249 = 8680490
271 + 8680219 = 8680490
277 + 8680213 = 8680490

Showing the first eight; more decompositions exist.
