Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599966, here are decompositions:

5 + 8599961 = 8599966
149 + 8599817 = 8599966
173 + 8599793 = 8599966
293 + 8599673 = 8599966
317 + 8599649 = 8599966
359 + 8599607 = 8599966
383 + 8599583 = 8599966
563 + 8599403 = 8599966

Showing the first eight; more decompositions exist.
