Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666750, here are decompositions:

3 + 8666747 = 8666750
67 + 8666683 = 8666750
271 + 8666479 = 8666750
307 + 8666443 = 8666750
331 + 8666419 = 8666750
577 + 8666173 = 8666750
613 + 8666137 = 8666750
691 + 8666059 = 8666750

Showing the first eight; more decompositions exist.
