Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31894, here are decompositions:

3 + 31891 = 31894
11 + 31883 = 31894
47 + 31847 = 31894
101 + 31793 = 31894
167 + 31727 = 31894
173 + 31721 = 31894
227 + 31667 = 31894
251 + 31643 = 31894

Showing the first eight; more decompositions exist.
