Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618224, here are decompositions:

3 + 8618221 = 8618224
11 + 8618213 = 8618224
137 + 8618087 = 8618224
191 + 8618033 = 8618224
233 + 8617991 = 8618224
281 + 8617943 = 8618224
347 + 8617877 = 8618224
353 + 8617871 = 8618224

Showing the first eight; more decompositions exist.
