Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82104, here are decompositions:

31 + 82073 = 82104
37 + 82067 = 82104
53 + 82051 = 82104
67 + 82037 = 82104
73 + 82031 = 82104
83 + 82021 = 82104
97 + 82007 = 82104
101 + 82003 = 82104

Showing the first eight; more decompositions exist.
