Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648224, here are decompositions:

3 + 8648221 = 8648224
113 + 8648111 = 8648224
131 + 8648093 = 8648224
191 + 8648033 = 8648224
227 + 8647997 = 8648224
257 + 8647967 = 8648224
311 + 8647913 = 8648224
401 + 8647823 = 8648224

Showing the first eight; more decompositions exist.
