Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663994, here are decompositions:

7 + 8663987 = 8663994
71 + 8663923 = 8663994
167 + 8663827 = 8663994
173 + 8663821 = 8663994
191 + 8663803 = 8663994
197 + 8663797 = 8663994
293 + 8663701 = 8663994
307 + 8663687 = 8663994

Showing the first eight; more decompositions exist.
