Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80386, here are decompositions:

17 + 80369 = 80386
23 + 80363 = 80386
107 + 80279 = 80386
113 + 80273 = 80386
179 + 80207 = 80386
233 + 80153 = 80386
239 + 80147 = 80386
347 + 80039 = 80386

Showing the first eight; more decompositions exist.
