Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487384, here are decompositions:

3 + 487381 = 487384
71 + 487313 = 487384
101 + 487283 = 487384
137 + 487247 = 487384
173 + 487211 = 487384
197 + 487187 = 487384
251 + 487133 = 487384
311 + 487073 = 487384

Showing the first eight; more decompositions exist.
