Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540680, here are decompositions:

3 + 540677 = 540680
61 + 540619 = 540680
67 + 540613 = 540680
103 + 540577 = 540680
139 + 540541 = 540680
163 + 540517 = 540680
211 + 540469 = 540680
307 + 540373 = 540680

Showing the first eight; more decompositions exist.
