Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470390, here are decompositions:

31 + 470359 = 470390
43 + 470347 = 470390
73 + 470317 = 470390
127 + 470263 = 470390
139 + 470251 = 470390
163 + 470227 = 470390
181 + 470209 = 470390
211 + 470179 = 470390

Showing the first eight; more decompositions exist.
