Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719128, here are decompositions:

29 + 8719099 = 8719128
71 + 8719057 = 8719128
79 + 8719049 = 8719128
97 + 8719031 = 8719128
107 + 8719021 = 8719128
179 + 8718949 = 8719128
211 + 8718917 = 8719128
241 + 8718887 = 8719128

Showing the first eight; more decompositions exist.
