Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637846, here are decompositions:

17 + 8637829 = 8637846
59 + 8637787 = 8637846
67 + 8637779 = 8637846
97 + 8637749 = 8637846
149 + 8637697 = 8637846
179 + 8637667 = 8637846
227 + 8637619 = 8637846
229 + 8637617 = 8637846

Showing the first eight; more decompositions exist.
