Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13894, here are decompositions:

11 + 13883 = 13894
17 + 13877 = 13894
53 + 13841 = 13894
113 + 13781 = 13894
131 + 13763 = 13894
137 + 13757 = 13894
173 + 13721 = 13894
197 + 13697 = 13894

Showing the first eight; more decompositions exist.
