Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640622, here are decompositions:

293 + 8640329 = 8640622
359 + 8640263 = 8640622
401 + 8640221 = 8640622
461 + 8640161 = 8640622
563 + 8640059 = 8640622
701 + 8639921 = 8640622
719 + 8639903 = 8640622
773 + 8639849 = 8640622

Showing the first eight; more decompositions exist.
