Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103870, here are decompositions:

3 + 103867 = 103870
29 + 103841 = 103870
59 + 103811 = 103870
83 + 103787 = 103870
101 + 103769 = 103870
167 + 103703 = 103870
227 + 103643 = 103870
251 + 103619 = 103870

Showing the first eight; more decompositions exist.
