Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643706, here are decompositions:

59 + 8643647 = 8643706
167 + 8643539 = 8643706
179 + 8643527 = 8643706
263 + 8643443 = 8643706
347 + 8643359 = 8643706
389 + 8643317 = 8643706
419 + 8643287 = 8643706
509 + 8643197 = 8643706

Showing the first eight; more decompositions exist.
