Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647622, here are decompositions:

43 + 8647579 = 8647622
163 + 8647459 = 8647622
211 + 8647411 = 8647622
229 + 8647393 = 8647622
349 + 8647273 = 8647622
439 + 8647183 = 8647622
499 + 8647123 = 8647622
601 + 8647021 = 8647622

Showing the first eight; more decompositions exist.
