Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487506, here are decompositions:

17 + 487489 = 487506
29 + 487477 = 487506
37 + 487469 = 487506
43 + 487463 = 487506
59 + 487447 = 487506
79 + 487427 = 487506
83 + 487423 = 487506
109 + 487397 = 487506

Showing the first eight; more decompositions exist.
