Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751918, here are decompositions:

11 + 8751907 = 8751918
31 + 8751887 = 8751918
47 + 8751871 = 8751918
59 + 8751859 = 8751918
79 + 8751839 = 8751918
89 + 8751829 = 8751918
101 + 8751817 = 8751918
137 + 8751781 = 8751918

Showing the first eight; more decompositions exist.
