Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470240, here are decompositions:

13 + 470227 = 470240
31 + 470209 = 470240
61 + 470179 = 470240
73 + 470167 = 470240
79 + 470161 = 470240
109 + 470131 = 470240
151 + 470089 = 470240
157 + 470083 = 470240

Showing the first eight; more decompositions exist.
