Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469980, here are decompositions:

11 + 469969 = 469980
23 + 469957 = 469980
41 + 469939 = 469980
61 + 469919 = 469980
73 + 469907 = 469980
89 + 469891 = 469980
101 + 469879 = 469980
103 + 469877 = 469980

Showing the first eight; more decompositions exist.
