Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756728, here are decompositions:

41 + 8756687 = 8756728
59 + 8756669 = 8756728
137 + 8756591 = 8756728
257 + 8756471 = 8756728
269 + 8756459 = 8756728
347 + 8756381 = 8756728
569 + 8756159 = 8756728
599 + 8756129 = 8756728

Showing the first eight; more decompositions exist.
