Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469902, here are decompositions:

11 + 469891 = 469902
23 + 469879 = 469902
53 + 469849 = 469902
61 + 469841 = 469902
79 + 469823 = 469902
101 + 469801 = 469902
109 + 469793 = 469902
149 + 469753 = 469902

Showing the first eight; more decompositions exist.
