Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103858, here are decompositions:

17 + 103841 = 103858
47 + 103811 = 103858
71 + 103787 = 103858
89 + 103769 = 103858
239 + 103619 = 103858
281 + 103577 = 103858
347 + 103511 = 103858
401 + 103457 = 103858

Showing the first eight; more decompositions exist.
