Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469390, here are decompositions:

11 + 469379 = 469390
23 + 469367 = 469390
59 + 469331 = 469390
107 + 469283 = 469390
137 + 469253 = 469390
149 + 469241 = 469390
197 + 469193 = 469390
263 + 469127 = 469390

Showing the first eight; more decompositions exist.
