Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591632, here are decompositions:

29 + 8591603 = 8591632
59 + 8591573 = 8591632
83 + 8591549 = 8591632
89 + 8591543 = 8591632
113 + 8591519 = 8591632
131 + 8591501 = 8591632
149 + 8591483 = 8591632
191 + 8591441 = 8591632

Showing the first eight; more decompositions exist.
