Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 461540, here are decompositions:

19 + 461521 = 461540
61 + 461479 = 461540
73 + 461467 = 461540
97 + 461443 = 461540
103 + 461437 = 461540
127 + 461413 = 461540
181 + 461359 = 461540
223 + 461317 = 461540

Showing the first eight; more decompositions exist.
