Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180266, here are decompositions:

3 + 180263 = 180266
7 + 180259 = 180266
19 + 180247 = 180266
193 + 180073 = 180266
223 + 180043 = 180266
277 + 179989 = 180266
313 + 179953 = 180266
349 + 179917 = 180266

Showing the first eight; more decompositions exist.
