Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470420, here are decompositions:

3 + 470417 = 470420
7 + 470413 = 470420
31 + 470389 = 470420
61 + 470359 = 470420
73 + 470347 = 470420
103 + 470317 = 470420
157 + 470263 = 470420
193 + 470227 = 470420

Showing the first eight; more decompositions exist.
