Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644366, here are decompositions:

113 + 8644253 = 8644366
179 + 8644187 = 8644366
317 + 8644049 = 8644366
347 + 8644019 = 8644366
443 + 8643923 = 8644366
569 + 8643797 = 8644366
587 + 8643779 = 8644366
617 + 8643749 = 8644366

Showing the first eight; more decompositions exist.
