Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488518, here are decompositions:

5 + 488513 = 488518
59 + 488459 = 488518
101 + 488417 = 488518
137 + 488381 = 488518
179 + 488339 = 488518
197 + 488321 = 488518
257 + 488261 = 488518
269 + 488249 = 488518

Showing the first eight; more decompositions exist.
