Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751018, here are decompositions:

5 + 8751013 = 8751018
11 + 8751007 = 8751018
61 + 8750957 = 8751018
71 + 8750947 = 8751018
97 + 8750921 = 8751018
127 + 8750891 = 8751018
137 + 8750881 = 8751018
151 + 8750867 = 8751018

Showing the first eight; more decompositions exist.
