Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751216, here are decompositions:

43 + 8751173 = 8751216
59 + 8751157 = 8751216
73 + 8751143 = 8751216
127 + 8751089 = 8751216
137 + 8751079 = 8751216
179 + 8751037 = 8751216
269 + 8750947 = 8751216
283 + 8750933 = 8751216

Showing the first eight; more decompositions exist.
