Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644486, here are decompositions:

29 + 8644457 = 8644486
47 + 8644439 = 8644486
89 + 8644397 = 8644486
233 + 8644253 = 8644486
467 + 8644019 = 8644486
563 + 8643923 = 8644486
593 + 8643893 = 8644486
647 + 8643839 = 8644486

Showing the first eight; more decompositions exist.
