Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488278, here are decompositions:

17 + 488261 = 488278
29 + 488249 = 488278
47 + 488231 = 488278
71 + 488207 = 488278
107 + 488171 = 488278
227 + 488051 = 488278
257 + 488021 = 488278
269 + 488009 = 488278

Showing the first eight; more decompositions exist.
