Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469180, here are decompositions:

11 + 469169 = 469180
53 + 469127 = 469180
59 + 469121 = 469180
149 + 469031 = 469180
197 + 468983 = 469180
227 + 468953 = 469180
281 + 468899 = 469180
293 + 468887 = 469180

Showing the first eight; more decompositions exist.
