Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617018, here are decompositions:

17 + 8617001 = 8617018
29 + 8616989 = 8617018
71 + 8616947 = 8617018
101 + 8616917 = 8617018
107 + 8616911 = 8617018
131 + 8616887 = 8617018
149 + 8616869 = 8617018
191 + 8616827 = 8617018

Showing the first eight; more decompositions exist.
