Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613982, here are decompositions:

23 + 8613959 = 8613982
29 + 8613953 = 8613982
53 + 8613929 = 8613982
71 + 8613911 = 8613982
89 + 8613893 = 8613982
131 + 8613851 = 8613982
173 + 8613809 = 8613982
239 + 8613743 = 8613982

Showing the first eight; more decompositions exist.
