Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663844, here are decompositions:

17 + 8663827 = 8663844
23 + 8663821 = 8663844
37 + 8663807 = 8663844
41 + 8663803 = 8663844
47 + 8663797 = 8663844
67 + 8663777 = 8663844
103 + 8663741 = 8663844
157 + 8663687 = 8663844

Showing the first eight; more decompositions exist.
