Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666942, here are decompositions:

3 + 8666939 = 8666942
61 + 8666881 = 8666942
79 + 8666863 = 8666942
103 + 8666839 = 8666942
409 + 8666533 = 8666942
463 + 8666479 = 8666942
499 + 8666443 = 8666942
523 + 8666419 = 8666942

Showing the first eight; more decompositions exist.
