Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101870, here are decompositions:

7 + 101863 = 101870
31 + 101839 = 101870
37 + 101833 = 101870
73 + 101797 = 101870
151 + 101719 = 101870
229 + 101641 = 101870
271 + 101599 = 101870
337 + 101533 = 101870

Showing the first eight; more decompositions exist.
