Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639846, here are decompositions:

37 + 8639809 = 8639846
43 + 8639803 = 8639846
67 + 8639779 = 8639846
73 + 8639773 = 8639846
97 + 8639749 = 8639846
199 + 8639647 = 8639846
283 + 8639563 = 8639846
307 + 8639539 = 8639846

Showing the first eight; more decompositions exist.
