Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626520, here are decompositions:

3 + 8626517 = 8626520
13 + 8626507 = 8626520
61 + 8626459 = 8626520
103 + 8626417 = 8626520
223 + 8626297 = 8626520
271 + 8626249 = 8626520
277 + 8626243 = 8626520
283 + 8626237 = 8626520

Showing the first eight; more decompositions exist.
