Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676942, here are decompositions:

5 + 8676937 = 8676942
59 + 8676883 = 8676942
163 + 8676779 = 8676942
173 + 8676769 = 8676942
191 + 8676751 = 8676942
199 + 8676743 = 8676942
223 + 8676719 = 8676942
251 + 8676691 = 8676942

Showing the first eight; more decompositions exist.
