Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82146, here are decompositions:

5 + 82141 = 82146
7 + 82139 = 82146
17 + 82129 = 82146
73 + 82073 = 82146
79 + 82067 = 82146
107 + 82039 = 82146
109 + 82037 = 82146
137 + 82009 = 82146

Showing the first eight; more decompositions exist.
