Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644426, here are decompositions:

29 + 8644397 = 8644426
173 + 8644253 = 8644426
239 + 8644187 = 8644426
269 + 8644157 = 8644426
467 + 8643959 = 8644426
503 + 8643923 = 8644426
587 + 8643839 = 8644426
647 + 8643779 = 8644426

Showing the first eight; more decompositions exist.
