Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640224, here are decompositions:

3 + 8640221 = 8640224
13 + 8640211 = 8640224
37 + 8640187 = 8640224
211 + 8640013 = 8640224
223 + 8640001 = 8640224
421 + 8639803 = 8640224
577 + 8639647 = 8640224
661 + 8639563 = 8640224

Showing the first eight; more decompositions exist.
