Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540644, here are decompositions:

31 + 540613 = 540644
67 + 540577 = 540644
103 + 540541 = 540644
127 + 540517 = 540644
211 + 540433 = 540644
271 + 540373 = 540644
277 + 540367 = 540644
337 + 540307 = 540644

Showing the first eight; more decompositions exist.
