Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622620, here are decompositions:

43 + 8622577 = 8622620
109 + 8622511 = 8622620
151 + 8622469 = 8622620
157 + 8622463 = 8622620
199 + 8622421 = 8622620
229 + 8622391 = 8622620
241 + 8622379 = 8622620
277 + 8622343 = 8622620

Showing the first eight; more decompositions exist.
