Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540732, here are decompositions:

19 + 540713 = 540732
29 + 540703 = 540732
41 + 540691 = 540732
43 + 540689 = 540732
53 + 540679 = 540732
103 + 540629 = 540732
113 + 540619 = 540732
173 + 540559 = 540732

Showing the first eight; more decompositions exist.
