Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469660, here are decompositions:

3 + 469657 = 469660
11 + 469649 = 469660
29 + 469631 = 469660
47 + 469613 = 469660
71 + 469589 = 469660
131 + 469529 = 469660
173 + 469487 = 469660
263 + 469397 = 469660

Showing the first eight; more decompositions exist.
