Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10870, here are decompositions:

3 + 10867 = 10870
11 + 10859 = 10870
17 + 10853 = 10870
23 + 10847 = 10870
71 + 10799 = 10870
89 + 10781 = 10870
131 + 10739 = 10870
137 + 10733 = 10870

Showing the first eight; more decompositions exist.
