Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488388, here are decompositions:

7 + 488381 = 488388
41 + 488347 = 488388
59 + 488329 = 488388
67 + 488321 = 488388
71 + 488317 = 488388
79 + 488309 = 488388
101 + 488287 = 488388
127 + 488261 = 488388

Showing the first eight; more decompositions exist.
