Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591720, here are decompositions:

3 + 8591717 = 8591720
31 + 8591689 = 8591720
37 + 8591683 = 8591720
97 + 8591623 = 8591720
103 + 8591617 = 8591720
127 + 8591593 = 8591720
157 + 8591563 = 8591720
271 + 8591449 = 8591720

Showing the first eight; more decompositions exist.
