Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83806, here are decompositions:

29 + 83777 = 83806
89 + 83717 = 83806
167 + 83639 = 83806
197 + 83609 = 83806
227 + 83579 = 83806
269 + 83537 = 83806
347 + 83459 = 83806
383 + 83423 = 83806

Showing the first eight; more decompositions exist.
