Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757224, here are decompositions:

37 + 8757187 = 8757224
97 + 8757127 = 8757224
103 + 8757121 = 8757224
163 + 8757061 = 8757224
211 + 8757013 = 8757224
241 + 8756983 = 8757224
271 + 8756953 = 8757224
277 + 8756947 = 8757224

Showing the first eight; more decompositions exist.
