Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636538, here are decompositions:

5 + 8636533 = 8636538
17 + 8636521 = 8636538
47 + 8636491 = 8636538
89 + 8636449 = 8636538
149 + 8636389 = 8636538
151 + 8636387 = 8636538
191 + 8636347 = 8636538
269 + 8636269 = 8636538

Showing the first eight; more decompositions exist.
