Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469540, here are decompositions:

11 + 469529 = 469540
53 + 469487 = 469540
83 + 469457 = 469540
101 + 469439 = 469540
173 + 469367 = 469540
257 + 469283 = 469540
311 + 469229 = 469540
347 + 469193 = 469540

Showing the first eight; more decompositions exist.
