Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7982, here are decompositions:

19 + 7963 = 7982
31 + 7951 = 7982
103 + 7879 = 7982
109 + 7873 = 7982
193 + 7789 = 7982
223 + 7759 = 7982
229 + 7753 = 7982
241 + 7741 = 7982

Showing the first eight; more decompositions exist.
