Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684540, here are decompositions:

3 + 8684537 = 8684540
19 + 8684521 = 8684540
37 + 8684503 = 8684540
61 + 8684479 = 8684540
79 + 8684461 = 8684540
103 + 8684437 = 8684540
181 + 8684359 = 8684540
199 + 8684341 = 8684540

Showing the first eight; more decompositions exist.
