Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487338, here are decompositions:

31 + 487307 = 487338
127 + 487211 = 487338
151 + 487187 = 487338
227 + 487111 = 487338
239 + 487099 = 487338
281 + 487057 = 487338
317 + 487021 = 487338
331 + 487007 = 487338

Showing the first eight; more decompositions exist.
