Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487684, here are decompositions:

3 + 487681 = 487684
47 + 487637 = 487684
83 + 487601 = 487684
227 + 487457 = 487684
257 + 487427 = 487684
293 + 487391 = 487684
401 + 487283 = 487684
677 + 487007 = 487684

Showing the first eight; more decompositions exist.
