Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730018, here are decompositions:

5 + 8730013 = 8730018
19 + 8729999 = 8730018
41 + 8729977 = 8730018
79 + 8729939 = 8730018
131 + 8729887 = 8730018
137 + 8729881 = 8730018
149 + 8729869 = 8730018
151 + 8729867 = 8730018

Showing the first eight; more decompositions exist.
