Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637894, here are decompositions:

47 + 8637847 = 8637894
73 + 8637821 = 8637894
103 + 8637791 = 8637894
107 + 8637787 = 8637894
193 + 8637701 = 8637894
197 + 8637697 = 8637894
227 + 8637667 = 8637894
257 + 8637637 = 8637894

Showing the first eight; more decompositions exist.
