Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751528, here are decompositions:

59 + 8751469 = 8751528
61 + 8751467 = 8751528
67 + 8751461 = 8751528
89 + 8751439 = 8751528
101 + 8751427 = 8751528
127 + 8751401 = 8751528
157 + 8751371 = 8751528
179 + 8751349 = 8751528

Showing the first eight; more decompositions exist.
