Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487284, here are decompositions:

23 + 487261 = 487284
37 + 487247 = 487284
71 + 487213 = 487284
73 + 487211 = 487284
97 + 487187 = 487284
101 + 487183 = 487284
107 + 487177 = 487284
151 + 487133 = 487284

Showing the first eight; more decompositions exist.
