Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488638, here are decompositions:

5 + 488633 = 488638
11 + 488627 = 488638
71 + 488567 = 488638
179 + 488459 = 488638
197 + 488441 = 488638
239 + 488399 = 488638
257 + 488381 = 488638
317 + 488321 = 488638

Showing the first eight; more decompositions exist.
