Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540078, here are decompositions:

17 + 540061 = 540078
37 + 540041 = 540078
131 + 539947 = 540078
157 + 539921 = 540078
179 + 539899 = 540078
181 + 539897 = 540078
197 + 539881 = 540078
229 + 539849 = 540078

Showing the first eight; more decompositions exist.
