Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540554, here are decompositions:

13 + 540541 = 540554
37 + 540517 = 540554
43 + 540511 = 540554
163 + 540391 = 540554
181 + 540373 = 540554
211 + 540343 = 540554
271 + 540283 = 540554
283 + 540271 = 540554

Showing the first eight; more decompositions exist.
