Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540458, here are decompositions:

67 + 540391 = 540458
109 + 540349 = 540458
151 + 540307 = 540458
157 + 540301 = 540458
241 + 540217 = 540458
271 + 540187 = 540458
277 + 540181 = 540458
337 + 540121 = 540458

Showing the first eight; more decompositions exist.
