Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470380, here are decompositions:

47 + 470333 = 470380
83 + 470297 = 470380
101 + 470279 = 470380
137 + 470243 = 470380
167 + 470213 = 470380
173 + 470207 = 470380
179 + 470201 = 470380
227 + 470153 = 470380

Showing the first eight; more decompositions exist.
