Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680066, here are decompositions:

23 + 8680043 = 8680066
29 + 8680037 = 8680066
113 + 8679953 = 8680066
167 + 8679899 = 8680066
179 + 8679887 = 8680066
389 + 8679677 = 8680066
449 + 8679617 = 8680066
509 + 8679557 = 8680066

Showing the first eight; more decompositions exist.
