Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487732, here are decompositions:

5 + 487727 = 487732
23 + 487709 = 487732
29 + 487703 = 487732
41 + 487691 = 487732
83 + 487649 = 487732
131 + 487601 = 487732
251 + 487481 = 487732
263 + 487469 = 487732

Showing the first eight; more decompositions exist.
