Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82078, here are decompositions:

5 + 82073 = 82078
11 + 82067 = 82078
41 + 82037 = 82078
47 + 82031 = 82078
71 + 82007 = 82078
107 + 81971 = 82078
149 + 81929 = 82078
179 + 81899 = 82078

Showing the first eight; more decompositions exist.
