Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470900, here are decompositions:

13 + 470887 = 470900
19 + 470881 = 470900
37 + 470863 = 470900
109 + 470791 = 470900
151 + 470749 = 470900
181 + 470719 = 470900
211 + 470689 = 470900
307 + 470593 = 470900

Showing the first eight; more decompositions exist.
