Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669822, here are decompositions:

151 + 8669671 = 8669822
193 + 8669629 = 8669822
199 + 8669623 = 8669822
211 + 8669611 = 8669822
229 + 8669593 = 8669822
379 + 8669443 = 8669822
433 + 8669389 = 8669822
571 + 8669251 = 8669822

Showing the first eight; more decompositions exist.
