Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488440, here are decompositions:

23 + 488417 = 488440
41 + 488399 = 488440
59 + 488381 = 488440
101 + 488339 = 488440
107 + 488333 = 488440
131 + 488309 = 488440
137 + 488303 = 488440
179 + 488261 = 488440

Showing the first eight; more decompositions exist.
