Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667426, here are decompositions:

7 + 8667419 = 8667426
13 + 8667413 = 8667426
23 + 8667403 = 8667426
107 + 8667319 = 8667426
113 + 8667313 = 8667426
127 + 8667299 = 8667426
137 + 8667289 = 8667426
199 + 8667227 = 8667426

Showing the first eight; more decompositions exist.
