Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676842, here are decompositions:

43 + 8676799 = 8676842
61 + 8676781 = 8676842
73 + 8676769 = 8676842
151 + 8676691 = 8676842
199 + 8676643 = 8676842
211 + 8676631 = 8676842
241 + 8676601 = 8676842
523 + 8676319 = 8676842

Showing the first eight; more decompositions exist.
