Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591832, here are decompositions:

5 + 8591827 = 8591832
19 + 8591813 = 8591832
23 + 8591809 = 8591832
59 + 8591773 = 8591832
61 + 8591771 = 8591832
149 + 8591683 = 8591832
199 + 8591633 = 8591832
229 + 8591603 = 8591832

Showing the first eight; more decompositions exist.
