Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591630, here are decompositions:

7 + 8591623 = 8591630
13 + 8591617 = 8591630
31 + 8591599 = 8591630
37 + 8591593 = 8591630
43 + 8591587 = 8591630
67 + 8591563 = 8591630
97 + 8591533 = 8591630
163 + 8591467 = 8591630

Showing the first eight; more decompositions exist.
