Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680664, here are decompositions:

151 + 8680513 = 8680664
163 + 8680501 = 8680664
193 + 8680471 = 8680664
337 + 8680327 = 8680664
367 + 8680297 = 8680664
397 + 8680267 = 8680664
463 + 8680201 = 8680664
631 + 8680033 = 8680664

Showing the first eight; more decompositions exist.
