Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655824, here are decompositions:

103 + 8655721 = 8655824
193 + 8655631 = 8655824
367 + 8655457 = 8655824
421 + 8655403 = 8655824
607 + 8655217 = 8655824
613 + 8655211 = 8655824
787 + 8655037 = 8655824
883 + 8654941 = 8655824

Showing the first eight; more decompositions exist.
