Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487494, here are decompositions:

5 + 487489 = 487494
13 + 487481 = 487494
17 + 487477 = 487494
23 + 487471 = 487494
31 + 487463 = 487494
37 + 487457 = 487494
47 + 487447 = 487494
67 + 487427 = 487494

Showing the first eight; more decompositions exist.
