Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540782, here are decompositions:

3 + 540779 = 540782
13 + 540769 = 540782
31 + 540751 = 540782
79 + 540703 = 540782
103 + 540679 = 540782
163 + 540619 = 540782
223 + 540559 = 540782
241 + 540541 = 540782

Showing the first eight; more decompositions exist.
