Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641894, here are decompositions:

3 + 8641891 = 8641894
11 + 8641883 = 8641894
113 + 8641781 = 8641894
197 + 8641697 = 8641894
251 + 8641643 = 8641894
263 + 8641631 = 8641894
281 + 8641613 = 8641894
347 + 8641547 = 8641894

Showing the first eight; more decompositions exist.
