Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622668, here are decompositions:

139 + 8622529 = 8622668
157 + 8622511 = 8622668
181 + 8622487 = 8622668
199 + 8622469 = 8622668
277 + 8622391 = 8622668
331 + 8622337 = 8622668
337 + 8622331 = 8622668
367 + 8622301 = 8622668

Showing the first eight; more decompositions exist.
