Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642622, here are decompositions:

31 + 8642591 = 8642622
41 + 8642581 = 8642622
89 + 8642533 = 8642622
103 + 8642519 = 8642622
113 + 8642509 = 8642622
173 + 8642449 = 8642622
193 + 8642429 = 8642622
239 + 8642383 = 8642622

Showing the first eight; more decompositions exist.
