Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487420, here are decompositions:

23 + 487397 = 487420
29 + 487391 = 487420
71 + 487349 = 487420
107 + 487313 = 487420
113 + 487307 = 487420
137 + 487283 = 487420
173 + 487247 = 487420
233 + 487187 = 487420

Showing the first eight; more decompositions exist.
