Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487646, here are decompositions:

43 + 487603 = 487646
139 + 487507 = 487646
157 + 487489 = 487646
199 + 487447 = 487646
223 + 487423 = 487646
283 + 487363 = 487646
433 + 487213 = 487646
463 + 487183 = 487646

Showing the first eight; more decompositions exist.
