Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676686, here are decompositions:

43 + 8676643 = 8676686
199 + 8676487 = 8676686
349 + 8676337 = 8676686
367 + 8676319 = 8676686
457 + 8676229 = 8676686
463 + 8676223 = 8676686
523 + 8676163 = 8676686
547 + 8676139 = 8676686

Showing the first eight; more decompositions exist.
