Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487406, here are decompositions:

19 + 487387 = 487406
43 + 487363 = 487406
103 + 487303 = 487406
193 + 487213 = 487406
223 + 487183 = 487406
229 + 487177 = 487406
307 + 487099 = 487406
313 + 487093 = 487406

Showing the first eight; more decompositions exist.
