Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540636, here are decompositions:

7 + 540629 = 540636
17 + 540619 = 540636
23 + 540613 = 540636
37 + 540599 = 540636
59 + 540577 = 540636
79 + 540557 = 540636
97 + 540539 = 540636
127 + 540509 = 540636

Showing the first eight; more decompositions exist.
