Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751506, here are decompositions:

3 + 8751503 = 8751506
13 + 8751493 = 8751506
37 + 8751469 = 8751506
67 + 8751439 = 8751506
79 + 8751427 = 8751506
139 + 8751367 = 8751506
157 + 8751349 = 8751506
349 + 8751157 = 8751506

Showing the first eight; more decompositions exist.
