Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670638, here are decompositions:

19 + 8670619 = 8670638
79 + 8670559 = 8670638
139 + 8670499 = 8670638
157 + 8670481 = 8670638
241 + 8670397 = 8670638
307 + 8670331 = 8670638
337 + 8670301 = 8670638
601 + 8670037 = 8670638

Showing the first eight; more decompositions exist.
