Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540728, here are decompositions:

31 + 540697 = 540728
37 + 540691 = 540728
109 + 540619 = 540728
151 + 540577 = 540728
211 + 540517 = 540728
337 + 540391 = 540728
379 + 540349 = 540728
421 + 540307 = 540728

Showing the first eight; more decompositions exist.
