Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11894, here are decompositions:

7 + 11887 = 11894
31 + 11863 = 11894
61 + 11833 = 11894
67 + 11827 = 11894
73 + 11821 = 11894
151 + 11743 = 11894
163 + 11731 = 11894
193 + 11701 = 11894

Showing the first eight; more decompositions exist.
