Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13904, here are decompositions:

3 + 13901 = 13904
31 + 13873 = 13904
73 + 13831 = 13904
97 + 13807 = 13904
181 + 13723 = 13904
193 + 13711 = 13904
211 + 13693 = 13904
223 + 13681 = 13904

Showing the first eight; more decompositions exist.
