Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616940, here are decompositions:

23 + 8616917 = 8616940
29 + 8616911 = 8616940
53 + 8616887 = 8616940
71 + 8616869 = 8616940
107 + 8616833 = 8616940
113 + 8616827 = 8616940
131 + 8616809 = 8616940
179 + 8616761 = 8616940

Showing the first eight; more decompositions exist.
