Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487540, here are decompositions:

59 + 487481 = 487540
71 + 487469 = 487540
83 + 487457 = 487540
113 + 487427 = 487540
149 + 487391 = 487540
191 + 487349 = 487540
227 + 487313 = 487540
233 + 487307 = 487540

Showing the first eight; more decompositions exist.
