Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469986, here are decompositions:

7 + 469979 = 469986
17 + 469969 = 469986
29 + 469957 = 469986
47 + 469939 = 469986
67 + 469919 = 469986
79 + 469907 = 469986
107 + 469879 = 469986
109 + 469877 = 469986

Showing the first eight; more decompositions exist.
