Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103894, here are decompositions:

5 + 103889 = 103894
53 + 103841 = 103894
83 + 103811 = 103894
107 + 103787 = 103894
191 + 103703 = 103894
251 + 103643 = 103894
281 + 103613 = 103894
311 + 103583 = 103894

Showing the first eight; more decompositions exist.
