Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616668, here are decompositions:

7 + 8616661 = 8616668
127 + 8616541 = 8616668
211 + 8616457 = 8616668
271 + 8616397 = 8616668
331 + 8616337 = 8616668
349 + 8616319 = 8616668
397 + 8616271 = 8616668
421 + 8616247 = 8616668

Showing the first eight; more decompositions exist.
