Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591786, here are decompositions:

13 + 8591773 = 8591786
97 + 8591689 = 8591786
103 + 8591683 = 8591786
163 + 8591623 = 8591786
193 + 8591593 = 8591786
199 + 8591587 = 8591786
223 + 8591563 = 8591786
337 + 8591449 = 8591786

Showing the first eight; more decompositions exist.
