Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488158, here are decompositions:

5 + 488153 = 488158
89 + 488069 = 488158
101 + 488057 = 488158
107 + 488051 = 488158
137 + 488021 = 488158
149 + 488009 = 488158
179 + 487979 = 488158
269 + 487889 = 488158

Showing the first eight; more decompositions exist.
