Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680458, here are decompositions:

19 + 8680439 = 8680458
41 + 8680417 = 8680458
67 + 8680391 = 8680458
79 + 8680379 = 8680458
89 + 8680369 = 8680458
131 + 8680327 = 8680458
151 + 8680307 = 8680458
181 + 8680277 = 8680458

Showing the first eight; more decompositions exist.
