Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644844, here are decompositions:

73 + 8644771 = 8644844
193 + 8644651 = 8644844
211 + 8644633 = 8644844
337 + 8644507 = 8644844
367 + 8644477 = 8644844
601 + 8644243 = 8644844
613 + 8644231 = 8644844
631 + 8644213 = 8644844

Showing the first eight; more decompositions exist.
