Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711870, here are decompositions:

3 + 8711867 = 8711870
7 + 8711863 = 8711870
19 + 8711851 = 8711870
73 + 8711797 = 8711870
103 + 8711767 = 8711870
127 + 8711743 = 8711870
151 + 8711719 = 8711870
163 + 8711707 = 8711870

Showing the first eight; more decompositions exist.
