Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469280, here are decompositions:

13 + 469267 = 469280
43 + 469237 = 469280
61 + 469219 = 469280
73 + 469207 = 469280
127 + 469153 = 469280
139 + 469141 = 469280
181 + 469099 = 469280
211 + 469069 = 469280

Showing the first eight; more decompositions exist.
