Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469138, here are decompositions:

11 + 469127 = 469138
17 + 469121 = 469138
101 + 469037 = 469138
107 + 469031 = 469138
239 + 468899 = 469138
251 + 468887 = 469138
269 + 468869 = 469138
317 + 468821 = 469138

Showing the first eight; more decompositions exist.
