Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618328, here are decompositions:

11 + 8618317 = 8618328
31 + 8618297 = 8618328
41 + 8618287 = 8618328
71 + 8618257 = 8618328
107 + 8618221 = 8618328
179 + 8618149 = 8618328
181 + 8618147 = 8618328
197 + 8618131 = 8618328

Showing the first eight; more decompositions exist.
