Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17894, here are decompositions:

3 + 17891 = 17894
13 + 17881 = 17894
31 + 17863 = 17894
43 + 17851 = 17894
67 + 17827 = 17894
103 + 17791 = 17894
157 + 17737 = 17894
181 + 17713 = 17894

Showing the first eight; more decompositions exist.
