Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488668, here are decompositions:

17 + 488651 = 488668
29 + 488639 = 488668
41 + 488627 = 488668
101 + 488567 = 488668
227 + 488441 = 488668
251 + 488417 = 488668
269 + 488399 = 488668
347 + 488321 = 488668

Showing the first eight; more decompositions exist.
