Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715224, here are decompositions:

31 + 8715193 = 8715224
43 + 8715181 = 8715224
73 + 8715151 = 8715224
211 + 8715013 = 8715224
241 + 8714983 = 8715224
277 + 8714947 = 8715224
283 + 8714941 = 8715224
367 + 8714857 = 8715224

Showing the first eight; more decompositions exist.
