Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81934, here are decompositions:

3 + 81931 = 81934
5 + 81929 = 81934
173 + 81761 = 81934
197 + 81737 = 81934
227 + 81707 = 81934
233 + 81701 = 81934
257 + 81677 = 81934
263 + 81671 = 81934

Showing the first eight; more decompositions exist.
