Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606988, here are decompositions:

29 + 8606959 = 8606988
31 + 8606957 = 8606988
59 + 8606929 = 8606988
79 + 8606909 = 8606988
149 + 8606839 = 8606988
191 + 8606797 = 8606988
199 + 8606789 = 8606988
251 + 8606737 = 8606988

Showing the first eight; more decompositions exist.
