Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487288, here are decompositions:

5 + 487283 = 487288
41 + 487247 = 487288
101 + 487187 = 487288
239 + 487049 = 487288
281 + 487007 = 487288
311 + 486977 = 487288
317 + 486971 = 487288
359 + 486929 = 487288

Showing the first eight; more decompositions exist.
