Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481666, here are decompositions:

47 + 481619 = 481666
89 + 481577 = 481666
197 + 481469 = 481666
233 + 481433 = 481666
257 + 481409 = 481666
293 + 481373 = 481666
359 + 481307 = 481666
467 + 481199 = 481666

Showing the first eight; more decompositions exist.
