Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667556, here are decompositions:

17 + 8667539 = 8667556
59 + 8667497 = 8667556
137 + 8667419 = 8667556
179 + 8667377 = 8667556
257 + 8667299 = 8667556
389 + 8667167 = 8667556
419 + 8667137 = 8667556
563 + 8666993 = 8667556

Showing the first eight; more decompositions exist.
