Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540280, here are decompositions:

11 + 540269 = 540280
29 + 540251 = 540280
47 + 540233 = 540280
101 + 540179 = 540280
107 + 540173 = 540280
113 + 540167 = 540280
131 + 540149 = 540280
179 + 540101 = 540280

Showing the first eight; more decompositions exist.
