Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680628, here are decompositions:

127 + 8680501 = 8680628
157 + 8680471 = 8680628
211 + 8680417 = 8680628
331 + 8680297 = 8680628
379 + 8680249 = 8680628
409 + 8680219 = 8680628
457 + 8680171 = 8680628
601 + 8680027 = 8680628

Showing the first eight; more decompositions exist.
