Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637958, here are decompositions:

5 + 8637953 = 8637958
29 + 8637929 = 8637958
89 + 8637869 = 8637958
137 + 8637821 = 8637958
167 + 8637791 = 8637958
179 + 8637779 = 8637958
257 + 8637701 = 8637958
317 + 8637641 = 8637958

Showing the first eight; more decompositions exist.
