Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751126, here are decompositions:

29 + 8751097 = 8751126
37 + 8751089 = 8751126
47 + 8751079 = 8751126
89 + 8751037 = 8751126
113 + 8751013 = 8751126
157 + 8750969 = 8751126
179 + 8750947 = 8751126
193 + 8750933 = 8751126

Showing the first eight; more decompositions exist.
