Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591636, here are decompositions:

3 + 8591633 = 8591636
13 + 8591623 = 8591636
19 + 8591617 = 8591636
37 + 8591599 = 8591636
43 + 8591593 = 8591636
73 + 8591563 = 8591636
103 + 8591533 = 8591636
337 + 8591299 = 8591636

Showing the first eight; more decompositions exist.
