Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42982, here are decompositions:

3 + 42979 = 42982
29 + 42953 = 42982
53 + 42929 = 42982
59 + 42923 = 42982
83 + 42899 = 42982
239 + 42743 = 42982
263 + 42719 = 42982
281 + 42701 = 42982

Showing the first eight; more decompositions exist.
