Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478516, here are decompositions:

23 + 478493 = 478516
83 + 478433 = 478516
89 + 478427 = 478516
113 + 478403 = 478516
173 + 478343 = 478516
257 + 478259 = 478516
263 + 478253 = 478516
317 + 478199 = 478516

Showing the first eight; more decompositions exist.
