Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180258, here are decompositions:

11 + 180247 = 180258
17 + 180241 = 180258
19 + 180239 = 180258
37 + 180221 = 180258
47 + 180211 = 180258
79 + 180179 = 180258
97 + 180161 = 180258
181 + 180077 = 180258

Showing the first eight; more decompositions exist.
