Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540820, here are decompositions:

11 + 540809 = 540820
17 + 540803 = 540820
41 + 540779 = 540820
47 + 540773 = 540820
107 + 540713 = 540820
131 + 540689 = 540820
191 + 540629 = 540820
233 + 540587 = 540820

Showing the first eight; more decompositions exist.
