Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676840, here are decompositions:

13 + 8676827 = 8676840
19 + 8676821 = 8676840
41 + 8676799 = 8676840
59 + 8676781 = 8676840
61 + 8676779 = 8676840
71 + 8676769 = 8676840
83 + 8676757 = 8676840
89 + 8676751 = 8676840

Showing the first eight; more decompositions exist.
