Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730020, here are decompositions:

7 + 8730013 = 8730020
37 + 8729983 = 8730020
43 + 8729977 = 8730020
97 + 8729923 = 8730020
139 + 8729881 = 8730020
151 + 8729869 = 8730020
181 + 8729839 = 8730020
199 + 8729821 = 8730020

Showing the first eight; more decompositions exist.
