Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750638, here are decompositions:

47 + 8750591 = 8750638
89 + 8750549 = 8750638
107 + 8750531 = 8750638
137 + 8750501 = 8750638
167 + 8750471 = 8750638
191 + 8750447 = 8750638
251 + 8750387 = 8750638
269 + 8750369 = 8750638

Showing the first eight; more decompositions exist.
