Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540648, here are decompositions:

19 + 540629 = 540648
29 + 540619 = 540648
37 + 540611 = 540648
61 + 540587 = 540648
71 + 540577 = 540648
89 + 540559 = 540648
107 + 540541 = 540648
109 + 540539 = 540648

Showing the first eight; more decompositions exist.
