Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470540, here are decompositions:

19 + 470521 = 470540
67 + 470473 = 470540
79 + 470461 = 470540
97 + 470443 = 470540
127 + 470413 = 470540
151 + 470389 = 470540
181 + 470359 = 470540
193 + 470347 = 470540

Showing the first eight; more decompositions exist.
