Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690238, here are decompositions:

17 + 8690221 = 8690238
47 + 8690191 = 8690238
61 + 8690177 = 8690238
149 + 8690089 = 8690238
197 + 8690041 = 8690238
241 + 8689997 = 8690238
251 + 8689987 = 8690238
257 + 8689981 = 8690238

Showing the first eight; more decompositions exist.
