Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171828, here are decompositions:

5 + 171823 = 171828
17 + 171811 = 171828
29 + 171799 = 171828
67 + 171761 = 171828
71 + 171757 = 171828
109 + 171719 = 171828
131 + 171697 = 171828
149 + 171679 = 171828

Showing the first eight; more decompositions exist.
