Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751020, here are decompositions:

7 + 8751013 = 8751020
13 + 8751007 = 8751020
73 + 8750947 = 8751020
79 + 8750941 = 8751020
97 + 8750923 = 8751020
127 + 8750893 = 8751020
139 + 8750881 = 8751020
163 + 8750857 = 8751020

Showing the first eight; more decompositions exist.
