Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82012, here are decompositions:

3 + 82009 = 82012
5 + 82007 = 82012
41 + 81971 = 82012
59 + 81953 = 82012
83 + 81929 = 82012
113 + 81899 = 82012
173 + 81839 = 82012
239 + 81773 = 82012

Showing the first eight; more decompositions exist.
