Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667266, here are decompositions:

163 + 8667103 = 8667266
277 + 8666989 = 8667266
313 + 8666953 = 8667266
457 + 8666809 = 8667266
499 + 8666767 = 8667266
733 + 8666533 = 8667266
787 + 8666479 = 8667266
823 + 8666443 = 8667266

Showing the first eight; more decompositions exist.
