Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540722, here are decompositions:

19 + 540703 = 540722
31 + 540691 = 540722
43 + 540679 = 540722
103 + 540619 = 540722
109 + 540613 = 540722
163 + 540559 = 540722
181 + 540541 = 540722
211 + 540511 = 540722

Showing the first eight; more decompositions exist.
