Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488528, here are decompositions:

109 + 488419 = 488528
127 + 488401 = 488528
181 + 488347 = 488528
199 + 488329 = 488528
211 + 488317 = 488528
241 + 488287 = 488528
331 + 488197 = 488528
367 + 488161 = 488528

Showing the first eight; more decompositions exist.
