Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643676, here are decompositions:

3 + 8643673 = 8643676
5 + 8643671 = 8643676
29 + 8643647 = 8643676
89 + 8643587 = 8643676
113 + 8643563 = 8643676
137 + 8643539 = 8643676
149 + 8643527 = 8643676
233 + 8643443 = 8643676

Showing the first eight; more decompositions exist.
