Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676680, here are decompositions:

37 + 8676643 = 8676680
79 + 8676601 = 8676680
139 + 8676541 = 8676680
163 + 8676517 = 8676680
193 + 8676487 = 8676680
283 + 8676397 = 8676680
379 + 8676301 = 8676680
457 + 8676223 = 8676680

Showing the first eight; more decompositions exist.
