Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758724, here are decompositions:

3 + 8758721 = 8758724
127 + 8758597 = 8758724
151 + 8758573 = 8758724
211 + 8758513 = 8758724
223 + 8758501 = 8758724
241 + 8758483 = 8758724
277 + 8758447 = 8758724
397 + 8758327 = 8758724

Showing the first eight; more decompositions exist.
