Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730000, here are decompositions:

17 + 8729983 = 8730000
23 + 8729977 = 8730000
61 + 8729939 = 8730000
113 + 8729887 = 8730000
131 + 8729869 = 8730000
151 + 8729849 = 8730000
163 + 8729837 = 8730000
179 + 8729821 = 8730000

Showing the first eight; more decompositions exist.
