Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690328, here are decompositions:

11 + 8690317 = 8690328
37 + 8690291 = 8690328
61 + 8690267 = 8690328
107 + 8690221 = 8690328
137 + 8690191 = 8690328
151 + 8690177 = 8690328
211 + 8690117 = 8690328
239 + 8690089 = 8690328

Showing the first eight; more decompositions exist.
