Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469878, here are decompositions:

29 + 469849 = 469878
37 + 469841 = 469878
67 + 469811 = 469878
109 + 469769 = 469878
131 + 469747 = 469878
191 + 469687 = 469878
229 + 469649 = 469878
251 + 469627 = 469878

Showing the first eight; more decompositions exist.
