Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487386, here are decompositions:

5 + 487381 = 487386
23 + 487363 = 487386
37 + 487349 = 487386
73 + 487313 = 487386
79 + 487307 = 487386
83 + 487303 = 487386
103 + 487283 = 487386
139 + 487247 = 487386

Showing the first eight; more decompositions exist.
