Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656724, here are decompositions:

3 + 8656721 = 8656724
151 + 8656573 = 8656724
163 + 8656561 = 8656724
313 + 8656411 = 8656724
331 + 8656393 = 8656724
367 + 8656357 = 8656724
547 + 8656177 = 8656724
577 + 8656147 = 8656724

Showing the first eight; more decompositions exist.
