Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80426, here are decompositions:

19 + 80407 = 80426
79 + 80347 = 80426
97 + 80329 = 80426
109 + 80317 = 80426
139 + 80287 = 80426
163 + 80263 = 80426
193 + 80233 = 80426
277 + 80149 = 80426

Showing the first eight; more decompositions exist.
