Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488458, here are decompositions:

17 + 488441 = 488458
41 + 488417 = 488458
59 + 488399 = 488458
137 + 488321 = 488458
149 + 488309 = 488458
197 + 488261 = 488458
227 + 488231 = 488458
251 + 488207 = 488458

Showing the first eight; more decompositions exist.
