Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540090, here are decompositions:

11 + 540079 = 540090
29 + 540061 = 540090
97 + 539993 = 540090
191 + 539899 = 540090
193 + 539897 = 540090
227 + 539863 = 540090
241 + 539849 = 540090
251 + 539839 = 540090

Showing the first eight; more decompositions exist.
