Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31982, here are decompositions:

19 + 31963 = 31982
109 + 31873 = 31982
211 + 31771 = 31982
241 + 31741 = 31982
283 + 31699 = 31982
409 + 31573 = 31982
439 + 31543 = 31982
661 + 31321 = 31982

Showing the first eight; more decompositions exist.
