Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487408, here are decompositions:

11 + 487397 = 487408
17 + 487391 = 487408
59 + 487349 = 487408
101 + 487307 = 487408
197 + 487211 = 487408
359 + 487049 = 487408
401 + 487007 = 487408
431 + 486977 = 487408

Showing the first eight; more decompositions exist.
