Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487486, here are decompositions:

5 + 487481 = 487486
17 + 487469 = 487486
23 + 487463 = 487486
29 + 487457 = 487486
59 + 487427 = 487486
89 + 487397 = 487486
137 + 487349 = 487486
173 + 487313 = 487486

Showing the first eight; more decompositions exist.
