Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591686, here are decompositions:

3 + 8591683 = 8591686
23 + 8591663 = 8591686
53 + 8591633 = 8591686
83 + 8591603 = 8591686
113 + 8591573 = 8591686
137 + 8591549 = 8591686
167 + 8591519 = 8591686
179 + 8591507 = 8591686

Showing the first eight; more decompositions exist.
