Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639608, here are decompositions:

11 + 8639597 = 8639608
17 + 8639591 = 8639608
41 + 8639567 = 8639608
59 + 8639549 = 8639608
101 + 8639507 = 8639608
149 + 8639459 = 8639608
167 + 8639441 = 8639608
227 + 8639381 = 8639608

Showing the first eight; more decompositions exist.
