Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488728, here are decompositions:

5 + 488723 = 488728
11 + 488717 = 488728
17 + 488711 = 488728
41 + 488687 = 488728
89 + 488639 = 488728
101 + 488627 = 488728
269 + 488459 = 488728
311 + 488417 = 488728

Showing the first eight; more decompositions exist.
