Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469870, here are decompositions:

29 + 469841 = 469870
47 + 469823 = 469870
59 + 469811 = 469870
83 + 469787 = 469870
101 + 469769 = 469870
113 + 469757 = 469870
179 + 469691 = 469870
197 + 469673 = 469870

Showing the first eight; more decompositions exist.
