Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487982, here are decompositions:

3 + 487979 = 487982
109 + 487873 = 487982
139 + 487843 = 487982
151 + 487831 = 487982
163 + 487819 = 487982
193 + 487789 = 487982
199 + 487783 = 487982
241 + 487741 = 487982

Showing the first eight; more decompositions exist.
