Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488118, here are decompositions:

61 + 488057 = 488118
67 + 488051 = 488118
97 + 488021 = 488118
107 + 488011 = 488118
109 + 488009 = 488118
139 + 487979 = 488118
227 + 487891 = 488118
229 + 487889 = 488118

Showing the first eight; more decompositions exist.
