Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470228, here are decompositions:

19 + 470209 = 470228
61 + 470167 = 470228
67 + 470161 = 470228
79 + 470149 = 470228
97 + 470131 = 470228
139 + 470089 = 470228
151 + 470077 = 470228
271 + 469957 = 470228

Showing the first eight; more decompositions exist.
