Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101864, here are decompositions:

31 + 101833 = 101864
67 + 101797 = 101864
127 + 101737 = 101864
163 + 101701 = 101864
211 + 101653 = 101864
223 + 101641 = 101864
283 + 101581 = 101864
331 + 101533 = 101864

Showing the first eight; more decompositions exist.
