Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540072, here are decompositions:

11 + 540061 = 540072
31 + 540041 = 540072
79 + 539993 = 540072
151 + 539921 = 540072
173 + 539899 = 540072
191 + 539881 = 540072
223 + 539849 = 540072
229 + 539843 = 540072

Showing the first eight; more decompositions exist.
