Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698638, here are decompositions:

5 + 8698633 = 8698638
17 + 8698621 = 8698638
41 + 8698597 = 8698638
79 + 8698559 = 8698638
89 + 8698549 = 8698638
139 + 8698499 = 8698638
181 + 8698457 = 8698638
239 + 8698399 = 8698638

Showing the first eight; more decompositions exist.
