Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656456, here are decompositions:

23 + 8656433 = 8656456
89 + 8656367 = 8656456
173 + 8656283 = 8656456
293 + 8656163 = 8656456
359 + 8656097 = 8656456
503 + 8655953 = 8656456
587 + 8655869 = 8656456
647 + 8655809 = 8656456

Showing the first eight; more decompositions exist.
