Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469900, here are decompositions:

23 + 469877 = 469900
59 + 469841 = 469900
89 + 469811 = 469900
107 + 469793 = 469900
113 + 469787 = 469900
131 + 469769 = 469900
227 + 469673 = 469900
251 + 469649 = 469900

Showing the first eight; more decompositions exist.
