Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639736, here are decompositions:

23 + 8639713 = 8639736
73 + 8639663 = 8639736
89 + 8639647 = 8639736
97 + 8639639 = 8639736
137 + 8639599 = 8639736
139 + 8639597 = 8639736
173 + 8639563 = 8639736
197 + 8639539 = 8639736

Showing the first eight; more decompositions exist.
