Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540842, here are decompositions:

19 + 540823 = 540842
61 + 540781 = 540842
73 + 540769 = 540842
139 + 540703 = 540842
151 + 540691 = 540842
163 + 540679 = 540842
223 + 540619 = 540842
229 + 540613 = 540842

Showing the first eight; more decompositions exist.
