Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80258, here are decompositions:

7 + 80251 = 80258
19 + 80239 = 80258
37 + 80221 = 80258
67 + 80191 = 80258
109 + 80149 = 80258
151 + 80107 = 80258
181 + 80077 = 80258
271 + 79987 = 80258

Showing the first eight; more decompositions exist.
