Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636540, here are decompositions:

7 + 8636533 = 8636540
19 + 8636521 = 8636540
67 + 8636473 = 8636540
151 + 8636389 = 8636540
163 + 8636377 = 8636540
193 + 8636347 = 8636540
271 + 8636269 = 8636540
277 + 8636263 = 8636540

Showing the first eight; more decompositions exist.
