Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468440, here are decompositions:

19 + 468421 = 468440
151 + 468289 = 468440
163 + 468277 = 468440
199 + 468241 = 468440
241 + 468199 = 468440
283 + 468157 = 468440
307 + 468133 = 468440
331 + 468109 = 468440

Showing the first eight; more decompositions exist.
