Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639418, here are decompositions:

5 + 8639413 = 8639418
17 + 8639401 = 8639418
37 + 8639381 = 8639418
71 + 8639347 = 8639418
127 + 8639291 = 8639418
157 + 8639261 = 8639418
167 + 8639251 = 8639418
191 + 8639227 = 8639418

Showing the first eight; more decompositions exist.
