Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469440, here are decompositions:

11 + 469429 = 469440
29 + 469411 = 469440
43 + 469397 = 469440
61 + 469379 = 469440
71 + 469369 = 469440
73 + 469367 = 469440
89 + 469351 = 469440
109 + 469331 = 469440

Showing the first eight; more decompositions exist.
