Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38870, here are decompositions:

3 + 38867 = 38870
19 + 38851 = 38870
31 + 38839 = 38870
37 + 38833 = 38870
67 + 38803 = 38870
79 + 38791 = 38870
103 + 38767 = 38870
157 + 38713 = 38870

Showing the first eight; more decompositions exist.
