Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676642, here are decompositions:

11 + 8676631 = 8676642
41 + 8676601 = 8676642
101 + 8676541 = 8676642
109 + 8676533 = 8676642
193 + 8676449 = 8676642
211 + 8676431 = 8676642
241 + 8676401 = 8676642
281 + 8676361 = 8676642

Showing the first eight; more decompositions exist.
