Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700224, here are decompositions:

31 + 8700193 = 8700224
103 + 8700121 = 8700224
193 + 8700031 = 8700224
223 + 8700001 = 8700224
271 + 8699953 = 8700224
277 + 8699947 = 8700224
307 + 8699917 = 8700224
331 + 8699893 = 8700224

Showing the first eight; more decompositions exist.
