Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105982, here are decompositions:

5 + 105977 = 105982
11 + 105971 = 105982
29 + 105953 = 105982
53 + 105929 = 105982
83 + 105899 = 105982
281 + 105701 = 105982
419 + 105563 = 105982
449 + 105533 = 105982

Showing the first eight; more decompositions exist.
