Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666732, here are decompositions:

199 + 8666533 = 8666732
241 + 8666491 = 8666732
313 + 8666419 = 8666732
409 + 8666323 = 8666732
463 + 8666269 = 8666732
673 + 8666059 = 8666732
709 + 8666023 = 8666732
733 + 8665999 = 8666732

Showing the first eight; more decompositions exist.
