Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540816, here are decompositions:

7 + 540809 = 540816
13 + 540803 = 540816
37 + 540779 = 540816
43 + 540773 = 540816
47 + 540769 = 540816
103 + 540713 = 540816
113 + 540703 = 540816
127 + 540689 = 540816

Showing the first eight; more decompositions exist.
