Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591628, here are decompositions:

5 + 8591623 = 8591628
11 + 8591617 = 8591628
29 + 8591599 = 8591628
41 + 8591587 = 8591628
79 + 8591549 = 8591628
109 + 8591519 = 8591628
127 + 8591501 = 8591628
179 + 8591449 = 8591628

Showing the first eight; more decompositions exist.
