Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680640, here are decompositions:

97 + 8680543 = 8680640
127 + 8680513 = 8680640
139 + 8680501 = 8680640
223 + 8680417 = 8680640
271 + 8680369 = 8680640
313 + 8680327 = 8680640
337 + 8680303 = 8680640
373 + 8680267 = 8680640

Showing the first eight; more decompositions exist.
