Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591826, here are decompositions:

13 + 8591813 = 8591826
17 + 8591809 = 8591826
53 + 8591773 = 8591826
79 + 8591747 = 8591826
109 + 8591717 = 8591826
137 + 8591689 = 8591826
163 + 8591663 = 8591826
193 + 8591633 = 8591826

Showing the first eight; more decompositions exist.
