Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639470, here are decompositions:

11 + 8639459 = 8639470
17 + 8639453 = 8639470
29 + 8639441 = 8639470
89 + 8639381 = 8639470
107 + 8639363 = 8639470
179 + 8639291 = 8639470
197 + 8639273 = 8639470
251 + 8639219 = 8639470

Showing the first eight; more decompositions exist.
