Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680580, here are decompositions:

37 + 8680543 = 8680580
67 + 8680513 = 8680580
79 + 8680501 = 8680580
109 + 8680471 = 8680580
163 + 8680417 = 8680580
211 + 8680369 = 8680580
277 + 8680303 = 8680580
283 + 8680297 = 8680580

Showing the first eight; more decompositions exist.
