Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488578, here are decompositions:

5 + 488573 = 488578
11 + 488567 = 488578
137 + 488441 = 488578
179 + 488399 = 488578
197 + 488381 = 488578
239 + 488339 = 488578
257 + 488321 = 488578
269 + 488309 = 488578

Showing the first eight; more decompositions exist.
