Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653540, here are decompositions:

3 + 8653537 = 8653540
11 + 8653529 = 8653540
23 + 8653517 = 8653540
53 + 8653487 = 8653540
83 + 8653457 = 8653540
167 + 8653373 = 8653540
179 + 8653361 = 8653540
197 + 8653343 = 8653540

Showing the first eight; more decompositions exist.
