Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488566, here are decompositions:

53 + 488513 = 488566
107 + 488459 = 488566
149 + 488417 = 488566
167 + 488399 = 488566
227 + 488339 = 488566
233 + 488333 = 488566
257 + 488309 = 488566
263 + 488303 = 488566

Showing the first eight; more decompositions exist.
