Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488628, here are decompositions:

11 + 488617 = 488628
17 + 488611 = 488628
61 + 488567 = 488628
89 + 488539 = 488628
211 + 488417 = 488628
227 + 488401 = 488628
229 + 488399 = 488628
281 + 488347 = 488628

Showing the first eight; more decompositions exist.
