Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469278, here are decompositions:

11 + 469267 = 469278
37 + 469241 = 469278
41 + 469237 = 469278
59 + 469219 = 469278
71 + 469207 = 469278
109 + 469169 = 469278
137 + 469141 = 469278
151 + 469127 = 469278

Showing the first eight; more decompositions exist.
