Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616918, here are decompositions:

5 + 8616913 = 8616918
7 + 8616911 = 8616918
17 + 8616901 = 8616918
31 + 8616887 = 8616918
59 + 8616859 = 8616918
97 + 8616821 = 8616918
109 + 8616809 = 8616918
137 + 8616781 = 8616918

Showing the first eight; more decompositions exist.
