Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719982, here are decompositions:

31 + 8719951 = 8719982
43 + 8719939 = 8719982
79 + 8719903 = 8719982
109 + 8719873 = 8719982
151 + 8719831 = 8719982
163 + 8719819 = 8719982
181 + 8719801 = 8719982
211 + 8719771 = 8719982

Showing the first eight; more decompositions exist.
