Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487966, here are decompositions:

23 + 487943 = 487966
137 + 487829 = 487966
173 + 487793 = 487966
197 + 487769 = 487966
233 + 487733 = 487966
239 + 487727 = 487966
257 + 487709 = 487966
263 + 487703 = 487966

Showing the first eight; more decompositions exist.
