Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668622, here are decompositions:

13 + 8668609 = 8668622
73 + 8668549 = 8668622
103 + 8668519 = 8668622
139 + 8668483 = 8668622
163 + 8668459 = 8668622
199 + 8668423 = 8668622
241 + 8668381 = 8668622
349 + 8668273 = 8668622

Showing the first eight; more decompositions exist.
