Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591806, here are decompositions:

59 + 8591747 = 8591806
89 + 8591717 = 8591806
173 + 8591633 = 8591806
233 + 8591573 = 8591806
257 + 8591549 = 8591806
263 + 8591543 = 8591806
479 + 8591327 = 8591806
569 + 8591237 = 8591806

Showing the first eight; more decompositions exist.
