Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72982, here are decompositions:

5 + 72977 = 72982
23 + 72959 = 72982
29 + 72953 = 72982
59 + 72923 = 72982
71 + 72911 = 72982
89 + 72893 = 72982
113 + 72869 = 72982
263 + 72719 = 72982

Showing the first eight; more decompositions exist.
