Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80298, here are decompositions:

11 + 80287 = 80298
19 + 80279 = 80298
47 + 80251 = 80298
59 + 80239 = 80298
67 + 80231 = 80298
89 + 80209 = 80298
107 + 80191 = 80298
131 + 80167 = 80298

Showing the first eight; more decompositions exist.
