Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82120, here are decompositions:

47 + 82073 = 82120
53 + 82067 = 82120
83 + 82037 = 82120
89 + 82031 = 82120
107 + 82013 = 82120
113 + 82007 = 82120
149 + 81971 = 82120
167 + 81953 = 82120

Showing the first eight; more decompositions exist.
