Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488188, here are decompositions:

17 + 488171 = 488188
131 + 488057 = 488188
137 + 488051 = 488188
167 + 488021 = 488188
179 + 488009 = 488188
191 + 487997 = 488188
359 + 487829 = 488188
419 + 487769 = 488188

Showing the first eight; more decompositions exist.
