Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643594, here are decompositions:

5 + 8643589 = 8643594
7 + 8643587 = 8643594
17 + 8643577 = 8643594
31 + 8643563 = 8643594
67 + 8643527 = 8643594
73 + 8643521 = 8643594
107 + 8643487 = 8643594
137 + 8643457 = 8643594

Showing the first eight; more decompositions exist.
