Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487244, here are decompositions:

31 + 487213 = 487244
61 + 487183 = 487244
67 + 487177 = 487244
151 + 487093 = 487244
193 + 487051 = 487244
223 + 487021 = 487244
337 + 486907 = 487244
463 + 486781 = 487244

Showing the first eight; more decompositions exist.
