Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730012, here are decompositions:

13 + 8729999 = 8730012
29 + 8729983 = 8730012
73 + 8729939 = 8730012
89 + 8729923 = 8730012
131 + 8729881 = 8730012
163 + 8729849 = 8730012
173 + 8729839 = 8730012
191 + 8729821 = 8730012

Showing the first eight; more decompositions exist.
