Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591722, here are decompositions:

5 + 8591717 = 8591722
11 + 8591711 = 8591722
59 + 8591663 = 8591722
89 + 8591633 = 8591722
149 + 8591573 = 8591722
173 + 8591549 = 8591722
179 + 8591543 = 8591722
239 + 8591483 = 8591722

Showing the first eight; more decompositions exist.
