Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540660, here are decompositions:

31 + 540629 = 540660
41 + 540619 = 540660
47 + 540613 = 540660
61 + 540599 = 540660
73 + 540587 = 540660
83 + 540577 = 540660
101 + 540559 = 540660
103 + 540557 = 540660

Showing the first eight; more decompositions exist.
