Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693438, here are decompositions:

31 + 8693407 = 8693438
37 + 8693401 = 8693438
157 + 8693281 = 8693438
181 + 8693257 = 8693438
211 + 8693227 = 8693438
241 + 8693197 = 8693438
277 + 8693161 = 8693438
307 + 8693131 = 8693438

Showing the first eight; more decompositions exist.
