Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667656, here are decompositions:

3 + 8667653 = 8667656
43 + 8667613 = 8667656
97 + 8667559 = 8667656
199 + 8667457 = 8667656
229 + 8667427 = 8667656
307 + 8667349 = 8667656
337 + 8667319 = 8667656
367 + 8667289 = 8667656

Showing the first eight; more decompositions exist.
