Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80286, here are decompositions:

7 + 80279 = 80286
13 + 80273 = 80286
23 + 80263 = 80286
47 + 80239 = 80286
53 + 80233 = 80286
79 + 80207 = 80286
109 + 80177 = 80286
113 + 80173 = 80286

Showing the first eight; more decompositions exist.
