Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613940, here are decompositions:

11 + 8613929 = 8613940
29 + 8613911 = 8613940
47 + 8613893 = 8613940
53 + 8613887 = 8613940
89 + 8613851 = 8613940
113 + 8613827 = 8613940
131 + 8613809 = 8613940
197 + 8613743 = 8613940

Showing the first eight; more decompositions exist.
