Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643736, here are decompositions:

29 + 8643707 = 8643736
89 + 8643647 = 8643736
149 + 8643587 = 8643736
173 + 8643563 = 8643736
197 + 8643539 = 8643736
293 + 8643443 = 8643736
419 + 8643317 = 8643736
449 + 8643287 = 8643736

Showing the first eight; more decompositions exist.
