Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649238, here are decompositions:

11 + 8649227 = 8649238
41 + 8649197 = 8649238
47 + 8649191 = 8649238
167 + 8649071 = 8649238
317 + 8648921 = 8649238
359 + 8648879 = 8649238
401 + 8648837 = 8649238
491 + 8648747 = 8649238

Showing the first eight; more decompositions exist.
