Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540800, here are decompositions:

19 + 540781 = 540800
31 + 540769 = 540800
97 + 540703 = 540800
103 + 540697 = 540800
109 + 540691 = 540800
181 + 540619 = 540800
223 + 540577 = 540800
241 + 540559 = 540800

Showing the first eight; more decompositions exist.
