Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487328, here are decompositions:

67 + 487261 = 487328
109 + 487219 = 487328
151 + 487177 = 487328
229 + 487099 = 487328
271 + 487057 = 487328
277 + 487051 = 487328
307 + 487021 = 487328
337 + 486991 = 487328

Showing the first eight; more decompositions exist.
