Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487438, here are decompositions:

11 + 487427 = 487438
41 + 487397 = 487438
47 + 487391 = 487438
89 + 487349 = 487438
131 + 487307 = 487438
191 + 487247 = 487438
227 + 487211 = 487438
251 + 487187 = 487438

Showing the first eight; more decompositions exist.
