Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591622, here are decompositions:

5 + 8591617 = 8591622
19 + 8591603 = 8591622
23 + 8591599 = 8591622
29 + 8591593 = 8591622
59 + 8591563 = 8591622
73 + 8591549 = 8591622
79 + 8591543 = 8591622
89 + 8591533 = 8591622

Showing the first eight; more decompositions exist.
