Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540686, here are decompositions:

7 + 540679 = 540686
67 + 540619 = 540686
73 + 540613 = 540686
109 + 540577 = 540686
127 + 540559 = 540686
313 + 540373 = 540686
337 + 540349 = 540686
379 + 540307 = 540686

Showing the first eight; more decompositions exist.
