Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643700, here are decompositions:

3 + 8643697 = 8643700
29 + 8643671 = 8643700
53 + 8643647 = 8643700
113 + 8643587 = 8643700
137 + 8643563 = 8643700
173 + 8643527 = 8643700
179 + 8643521 = 8643700
257 + 8643443 = 8643700

Showing the first eight; more decompositions exist.
