Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746666, here are decompositions:

29 + 8746637 = 8746666
197 + 8746469 = 8746666
239 + 8746427 = 8746666
443 + 8746223 = 8746666
743 + 8745923 = 8746666
809 + 8745857 = 8746666
839 + 8745827 = 8746666
983 + 8745683 = 8746666

Showing the first eight; more decompositions exist.
