Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604978, here are decompositions:

17 + 8604961 = 8604978
167 + 8604811 = 8604978
181 + 8604797 = 8604978
197 + 8604781 = 8604978
199 + 8604779 = 8604978
211 + 8604767 = 8604978
227 + 8604751 = 8604978
229 + 8604749 = 8604978

Showing the first eight; more decompositions exist.
