Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676870, here are decompositions:

23 + 8676847 = 8676870
43 + 8676827 = 8676870
71 + 8676799 = 8676870
89 + 8676781 = 8676870
101 + 8676769 = 8676870
113 + 8676757 = 8676870
127 + 8676743 = 8676870
149 + 8676721 = 8676870

Showing the first eight; more decompositions exist.
