Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487250, here are decompositions:

3 + 487247 = 487250
31 + 487219 = 487250
37 + 487213 = 487250
67 + 487183 = 487250
73 + 487177 = 487250
139 + 487111 = 487250
151 + 487099 = 487250
157 + 487093 = 487250

Showing the first eight; more decompositions exist.
