Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613918, here are decompositions:

7 + 8613911 = 8613918
31 + 8613887 = 8613918
67 + 8613851 = 8613918
101 + 8613817 = 8613918
107 + 8613811 = 8613918
109 + 8613809 = 8613918
167 + 8613751 = 8613918
179 + 8613739 = 8613918

Showing the first eight; more decompositions exist.
