Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180466, here are decompositions:

3 + 180463 = 180466
29 + 180437 = 180466
47 + 180419 = 180466
53 + 180413 = 180466
149 + 180317 = 180466
179 + 180287 = 180466
227 + 180239 = 180466
233 + 180233 = 180466

Showing the first eight; more decompositions exist.
