Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646894, here are decompositions:

5 + 8646889 = 8646894
41 + 8646853 = 8646894
43 + 8646851 = 8646894
71 + 8646823 = 8646894
73 + 8646821 = 8646894
101 + 8646793 = 8646894
173 + 8646721 = 8646894
211 + 8646683 = 8646894

Showing the first eight; more decompositions exist.
