Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540066, here are decompositions:

5 + 540061 = 540066
73 + 539993 = 540066
167 + 539899 = 540066
223 + 539843 = 540066
227 + 539839 = 540066
229 + 539837 = 540066
269 + 539797 = 540066
283 + 539783 = 540066

Showing the first eight; more decompositions exist.
