Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80558, here are decompositions:

31 + 80527 = 80558
67 + 80491 = 80558
109 + 80449 = 80558
151 + 80407 = 80558
211 + 80347 = 80558
229 + 80329 = 80558
241 + 80317 = 80558
271 + 80287 = 80558

Showing the first eight; more decompositions exist.
