Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641224, here are decompositions:

13 + 8641211 = 8641224
37 + 8641187 = 8641224
127 + 8641097 = 8641224
131 + 8641093 = 8641224
257 + 8640967 = 8641224
313 + 8640911 = 8641224
337 + 8640887 = 8641224
353 + 8640871 = 8641224

Showing the first eight; more decompositions exist.
