Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540918, here are decompositions:

11 + 540907 = 540918
17 + 540901 = 540918
41 + 540877 = 540918
47 + 540871 = 540918
67 + 540851 = 540918
109 + 540809 = 540918
137 + 540781 = 540918
139 + 540779 = 540918

Showing the first eight; more decompositions exist.
