Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469478, here are decompositions:

67 + 469411 = 469478
109 + 469369 = 469478
127 + 469351 = 469478
157 + 469321 = 469478
199 + 469279 = 469478
211 + 469267 = 469478
241 + 469237 = 469478
271 + 469207 = 469478

Showing the first eight; more decompositions exist.
