Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540080, here are decompositions:

19 + 540061 = 540080
181 + 539899 = 540080
199 + 539881 = 540080
241 + 539839 = 540080
283 + 539797 = 540080
337 + 539743 = 540080
367 + 539713 = 540080
439 + 539641 = 540080

Showing the first eight; more decompositions exist.
