Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488028, here are decompositions:

7 + 488021 = 488028
17 + 488011 = 488028
19 + 488009 = 488028
31 + 487997 = 488028
131 + 487897 = 488028
137 + 487891 = 488028
139 + 487889 = 488028
197 + 487831 = 488028

Showing the first eight; more decompositions exist.
