Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469438, here are decompositions:

41 + 469397 = 469438
59 + 469379 = 469438
71 + 469367 = 469438
107 + 469331 = 469438
197 + 469241 = 469438
269 + 469169 = 469438
311 + 469127 = 469438
317 + 469121 = 469438

Showing the first eight; more decompositions exist.
