Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487810, here are decompositions:

17 + 487793 = 487810
41 + 487769 = 487810
53 + 487757 = 487810
83 + 487727 = 487810
101 + 487709 = 487810
107 + 487703 = 487810
173 + 487637 = 487810
347 + 487463 = 487810

Showing the first eight; more decompositions exist.
