Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540828, here are decompositions:

5 + 540823 = 540828
19 + 540809 = 540828
47 + 540781 = 540828
59 + 540769 = 540828
131 + 540697 = 540828
137 + 540691 = 540828
139 + 540689 = 540828
149 + 540679 = 540828

Showing the first eight; more decompositions exist.
