Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103892, here are decompositions:

3 + 103889 = 103892
79 + 103813 = 103892
193 + 103699 = 103892
211 + 103681 = 103892
223 + 103669 = 103892
241 + 103651 = 103892
331 + 103561 = 103892
409 + 103483 = 103892

Showing the first eight; more decompositions exist.
