Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591906, here are decompositions:

7 + 8591899 = 8591906
19 + 8591887 = 8591906
79 + 8591827 = 8591906
97 + 8591809 = 8591906
223 + 8591683 = 8591906
283 + 8591623 = 8591906
307 + 8591599 = 8591906
313 + 8591593 = 8591906

Showing the first eight; more decompositions exist.
