Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730828, here are decompositions:

31 + 8730797 = 8730828
47 + 8730781 = 8730828
131 + 8730697 = 8730828
137 + 8730691 = 8730828
167 + 8730661 = 8730828
179 + 8730649 = 8730828
199 + 8730629 = 8730828
251 + 8730577 = 8730828

Showing the first eight; more decompositions exist.
