Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687966, here are decompositions:

3 + 8687963 = 8687966
13 + 8687953 = 8687966
37 + 8687929 = 8687966
43 + 8687923 = 8687966
139 + 8687827 = 8687966
307 + 8687659 = 8687966
367 + 8687599 = 8687966
379 + 8687587 = 8687966

Showing the first eight; more decompositions exist.
