Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644382, here are decompositions:

139 + 8644243 = 8644382
151 + 8644231 = 8644382
211 + 8644171 = 8644382
463 + 8643919 = 8644382
661 + 8643721 = 8644382
709 + 8643673 = 8644382
751 + 8643631 = 8644382
1039 + 8643343 = 8644382

Showing the first eight; more decompositions exist.
