Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751224, here are decompositions:

3 + 8751221 = 8751224
43 + 8751181 = 8751224
67 + 8751157 = 8751224
73 + 8751151 = 8751224
127 + 8751097 = 8751224
211 + 8751013 = 8751224
277 + 8750947 = 8751224
283 + 8750941 = 8751224

Showing the first eight; more decompositions exist.
