Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28982, here are decompositions:

3 + 28979 = 28982
61 + 28921 = 28982
73 + 28909 = 28982
103 + 28879 = 28982
139 + 28843 = 28982
193 + 28789 = 28982
211 + 28771 = 28982
223 + 28759 = 28982

Showing the first eight; more decompositions exist.
