Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8870, here are decompositions:

3 + 8867 = 8870
7 + 8863 = 8870
31 + 8839 = 8870
67 + 8803 = 8870
109 + 8761 = 8870
139 + 8731 = 8870
151 + 8719 = 8870
157 + 8713 = 8870

Showing the first eight; more decompositions exist.
