Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488146, here are decompositions:

3 + 488143 = 488146
89 + 488057 = 488146
137 + 488009 = 488146
149 + 487997 = 488146
167 + 487979 = 488146
173 + 487973 = 488146
257 + 487889 = 488146
317 + 487829 = 488146

Showing the first eight; more decompositions exist.
