Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680684, here are decompositions:

53 + 8680631 = 8680684
71 + 8680613 = 8680684
83 + 8680601 = 8680684
101 + 8680583 = 8680684
293 + 8680391 = 8680684
347 + 8680337 = 8680684
563 + 8680121 = 8680684
641 + 8680043 = 8680684

Showing the first eight; more decompositions exist.
