Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699638, here are decompositions:

5 + 8699633 = 8699638
71 + 8699567 = 8699638
137 + 8699501 = 8699638
149 + 8699489 = 8699638
251 + 8699387 = 8699638
257 + 8699381 = 8699638
359 + 8699279 = 8699638
401 + 8699237 = 8699638

Showing the first eight; more decompositions exist.
