Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487984, here are decompositions:

5 + 487979 = 487984
11 + 487973 = 487984
41 + 487943 = 487984
173 + 487811 = 487984
191 + 487793 = 487984
227 + 487757 = 487984
251 + 487733 = 487984
257 + 487727 = 487984

Showing the first eight; more decompositions exist.
