Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643846, here are decompositions:

7 + 8643839 = 8643846
59 + 8643787 = 8643846
67 + 8643779 = 8643846
89 + 8643757 = 8643846
97 + 8643749 = 8643846
139 + 8643707 = 8643846
149 + 8643697 = 8643846
173 + 8643673 = 8643846

Showing the first eight; more decompositions exist.
