Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667826, here are decompositions:

5 + 8667821 = 8667826
17 + 8667809 = 8667826
29 + 8667797 = 8667826
137 + 8667689 = 8667826
149 + 8667677 = 8667826
173 + 8667653 = 8667826
263 + 8667563 = 8667826
449 + 8667377 = 8667826

Showing the first eight; more decompositions exist.
