Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487864, here are decompositions:

53 + 487811 = 487864
71 + 487793 = 487864
107 + 487757 = 487864
131 + 487733 = 487864
137 + 487727 = 487864
173 + 487691 = 487864
227 + 487637 = 487864
257 + 487607 = 487864

Showing the first eight; more decompositions exist.
