Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487458, here are decompositions:

11 + 487447 = 487458
29 + 487429 = 487458
31 + 487427 = 487458
61 + 487397 = 487458
67 + 487391 = 487458
71 + 487387 = 487458
109 + 487349 = 487458
151 + 487307 = 487458

Showing the first eight; more decompositions exist.
