Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540724, here are decompositions:

11 + 540713 = 540724
47 + 540677 = 540724
113 + 540611 = 540724
137 + 540587 = 540724
167 + 540557 = 540724
263 + 540461 = 540724
347 + 540377 = 540724
491 + 540233 = 540724

Showing the first eight; more decompositions exist.
