Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487726, here are decompositions:

17 + 487709 = 487726
23 + 487703 = 487726
89 + 487637 = 487726
137 + 487589 = 487726
257 + 487469 = 487726
263 + 487463 = 487726
269 + 487457 = 487726
419 + 487307 = 487726

Showing the first eight; more decompositions exist.
