Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487666, here are decompositions:

17 + 487649 = 487666
29 + 487637 = 487666
59 + 487607 = 487666
197 + 487469 = 487666
239 + 487427 = 487666
269 + 487397 = 487666
317 + 487349 = 487666
353 + 487313 = 487666

Showing the first eight; more decompositions exist.
