Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658224, here are decompositions:

7 + 8658217 = 8658224
31 + 8658193 = 8658224
181 + 8658043 = 8658224
241 + 8657983 = 8658224
373 + 8657851 = 8658224
397 + 8657827 = 8658224
457 + 8657767 = 8658224
613 + 8657611 = 8658224

Showing the first eight; more decompositions exist.
