Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543540, here are decompositions:

31 + 543509 = 543540
37 + 543503 = 543540
43 + 543497 = 543540
113 + 543427 = 543540
157 + 543383 = 543540
181 + 543359 = 543540
191 + 543349 = 543540
199 + 543341 = 543540

Showing the first eight; more decompositions exist.
