Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540666, here are decompositions:

37 + 540629 = 540666
47 + 540619 = 540666
53 + 540613 = 540666
67 + 540599 = 540666
79 + 540587 = 540666
89 + 540577 = 540666
107 + 540559 = 540666
109 + 540557 = 540666

Showing the first eight; more decompositions exist.
