Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632540, here are decompositions:

11 + 8632529 = 8632540
17 + 8632523 = 8632540
47 + 8632493 = 8632540
53 + 8632487 = 8632540
83 + 8632457 = 8632540
89 + 8632451 = 8632540
149 + 8632391 = 8632540
173 + 8632367 = 8632540

Showing the first eight; more decompositions exist.
