Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470180, here are decompositions:

13 + 470167 = 470180
19 + 470161 = 470180
31 + 470149 = 470180
97 + 470083 = 470180
103 + 470077 = 470180
211 + 469969 = 470180
223 + 469957 = 470180
241 + 469939 = 470180

Showing the first eight; more decompositions exist.
