Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540140, here are decompositions:

19 + 540121 = 540140
61 + 540079 = 540140
79 + 540061 = 540140
193 + 539947 = 540140
241 + 539899 = 540140
277 + 539863 = 540140
379 + 539761 = 540140
397 + 539743 = 540140

Showing the first eight; more decompositions exist.
