Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540126, here are decompositions:

5 + 540121 = 540126
7 + 540119 = 540126
47 + 540079 = 540126
179 + 539947 = 540126
227 + 539899 = 540126
229 + 539897 = 540126
263 + 539863 = 540126
277 + 539849 = 540126

Showing the first eight; more decompositions exist.
