Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647216, here are decompositions:

23 + 8647193 = 8647216
59 + 8647157 = 8647216
89 + 8647127 = 8647216
173 + 8647043 = 8647216
269 + 8646947 = 8647216
317 + 8646899 = 8647216
509 + 8646707 = 8647216
719 + 8646497 = 8647216

Showing the first eight; more decompositions exist.
