Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621224, here are decompositions:

11 + 8621213 = 8621224
23 + 8621201 = 8621224
41 + 8621183 = 8621224
71 + 8621153 = 8621224
137 + 8621087 = 8621224
173 + 8621051 = 8621224
251 + 8620973 = 8621224
281 + 8620943 = 8621224

Showing the first eight; more decompositions exist.
