Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541828, here are decompositions:

11 + 541817 = 541828
29 + 541799 = 541828
47 + 541781 = 541828
101 + 541727 = 541828
107 + 541721 = 541828
167 + 541661 = 541828
197 + 541631 = 541828
239 + 541589 = 541828

Showing the first eight; more decompositions exist.
