Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12982, here are decompositions:

3 + 12979 = 12982
23 + 12959 = 12982
29 + 12953 = 12982
41 + 12941 = 12982
59 + 12923 = 12982
71 + 12911 = 12982
83 + 12899 = 12982
89 + 12893 = 12982

Showing the first eight; more decompositions exist.
