Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644244, here are decompositions:

13 + 8644231 = 8644244
31 + 8644213 = 8644244
73 + 8644171 = 8644244
97 + 8644147 = 8644244
163 + 8644081 = 8644244
457 + 8643787 = 8644244
487 + 8643757 = 8644244
523 + 8643721 = 8644244

Showing the first eight; more decompositions exist.
