Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687996, here are decompositions:

3 + 8687993 = 8687996
13 + 8687983 = 8687996
43 + 8687953 = 8687996
67 + 8687929 = 8687996
73 + 8687923 = 8687996
199 + 8687797 = 8687996
283 + 8687713 = 8687996
337 + 8687659 = 8687996

Showing the first eight; more decompositions exist.
