Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488486, here are decompositions:

13 + 488473 = 488486
67 + 488419 = 488486
79 + 488407 = 488486
139 + 488347 = 488486
157 + 488329 = 488486
199 + 488287 = 488486
223 + 488263 = 488486
277 + 488209 = 488486

Showing the first eight; more decompositions exist.
