Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82156, here are decompositions:

3 + 82153 = 82156
17 + 82139 = 82156
83 + 82073 = 82156
89 + 82067 = 82156
149 + 82007 = 82156
227 + 81929 = 82156
257 + 81899 = 82156
317 + 81839 = 82156

Showing the first eight; more decompositions exist.
