Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750728, here are decompositions:

71 + 8750657 = 8750728
89 + 8750639 = 8750728
137 + 8750591 = 8750728
179 + 8750549 = 8750728
197 + 8750531 = 8750728
227 + 8750501 = 8750728
257 + 8750471 = 8750728
281 + 8750447 = 8750728

Showing the first eight; more decompositions exist.
