Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540398, here are decompositions:

7 + 540391 = 540398
31 + 540367 = 540398
97 + 540301 = 540398
127 + 540271 = 540398
181 + 540217 = 540398
211 + 540187 = 540398
241 + 540157 = 540398
277 + 540121 = 540398

Showing the first eight; more decompositions exist.
