Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469806, here are decompositions:

5 + 469801 = 469806
13 + 469793 = 469806
19 + 469787 = 469806
37 + 469769 = 469806
53 + 469753 = 469806
59 + 469747 = 469806
83 + 469723 = 469806
89 + 469717 = 469806

Showing the first eight; more decompositions exist.
