Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487318, here are decompositions:

5 + 487313 = 487318
11 + 487307 = 487318
71 + 487247 = 487318
107 + 487211 = 487318
131 + 487187 = 487318
239 + 487079 = 487318
269 + 487049 = 487318
311 + 487007 = 487318

Showing the first eight; more decompositions exist.
