Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750538, here are decompositions:

7 + 8750531 = 8750538
11 + 8750527 = 8750538
19 + 8750519 = 8750538
29 + 8750509 = 8750538
37 + 8750501 = 8750538
47 + 8750491 = 8750538
59 + 8750479 = 8750538
67 + 8750471 = 8750538

Showing the first eight; more decompositions exist.
