Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680538, here are decompositions:

37 + 8680501 = 8680538
67 + 8680471 = 8680538
211 + 8680327 = 8680538
241 + 8680297 = 8680538
271 + 8680267 = 8680538
337 + 8680201 = 8680538
367 + 8680171 = 8680538
439 + 8680099 = 8680538

Showing the first eight; more decompositions exist.
