Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80506, here are decompositions:

17 + 80489 = 80506
59 + 80447 = 80506
137 + 80369 = 80506
197 + 80309 = 80506
227 + 80279 = 80506
233 + 80273 = 80506
353 + 80153 = 80506
359 + 80147 = 80506

Showing the first eight; more decompositions exist.
