Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153828, here are decompositions:

11 + 153817 = 153828
71 + 153757 = 153828
79 + 153749 = 153828
89 + 153739 = 153828
109 + 153719 = 153828
127 + 153701 = 153828
139 + 153689 = 153828
179 + 153649 = 153828

Showing the first eight; more decompositions exist.
