Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126828, here are decompositions:

5 + 126823 = 126828
47 + 126781 = 126828
67 + 126761 = 126828
71 + 126757 = 126828
89 + 126739 = 126828
109 + 126719 = 126828
137 + 126691 = 126828
197 + 126631 = 126828

Showing the first eight; more decompositions exist.
