Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27982, here are decompositions:

29 + 27953 = 27982
41 + 27941 = 27982
89 + 27893 = 27982
131 + 27851 = 27982
173 + 27809 = 27982
179 + 27803 = 27982
191 + 27791 = 27982
233 + 27749 = 27982

Showing the first eight; more decompositions exist.
