Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465440, here are decompositions:

7 + 465433 = 465440
61 + 465379 = 465440
67 + 465373 = 465440
103 + 465337 = 465440
109 + 465331 = 465440
163 + 465277 = 465440
181 + 465259 = 465440
229 + 465211 = 465440

Showing the first eight; more decompositions exist.
