Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487876, here are decompositions:

3 + 487873 = 487876
47 + 487829 = 487876
83 + 487793 = 487876
107 + 487769 = 487876
149 + 487727 = 487876
167 + 487709 = 487876
173 + 487703 = 487876
227 + 487649 = 487876

Showing the first eight; more decompositions exist.
