Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617668, here are decompositions:

41 + 8617627 = 8617668
107 + 8617561 = 8617668
149 + 8617519 = 8617668
229 + 8617439 = 8617668
251 + 8617417 = 8617668
271 + 8617397 = 8617668
277 + 8617391 = 8617668
307 + 8617361 = 8617668

Showing the first eight; more decompositions exist.
