Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465280, here are decompositions:

3 + 465277 = 465280
71 + 465209 = 465280
107 + 465173 = 465280
113 + 465167 = 465280
173 + 465107 = 465280
191 + 465089 = 465280
239 + 465041 = 465280
269 + 465011 = 465280

Showing the first eight; more decompositions exist.
