Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591730, here are decompositions:

13 + 8591717 = 8591730
19 + 8591711 = 8591730
41 + 8591689 = 8591730
47 + 8591683 = 8591730
67 + 8591663 = 8591730
97 + 8591633 = 8591730
107 + 8591623 = 8591730
113 + 8591617 = 8591730

Showing the first eight; more decompositions exist.
