Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80280, here are decompositions:

7 + 80273 = 80280
17 + 80263 = 80280
29 + 80251 = 80280
41 + 80239 = 80280
47 + 80233 = 80280
59 + 80221 = 80280
71 + 80209 = 80280
73 + 80207 = 80280

Showing the first eight; more decompositions exist.
