Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19982, here are decompositions:

3 + 19979 = 19982
19 + 19963 = 19982
139 + 19843 = 19982
163 + 19819 = 19982
181 + 19801 = 19982
223 + 19759 = 19982
229 + 19753 = 19982
283 + 19699 = 19982

Showing the first eight; more decompositions exist.
