Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180382, here are decompositions:

3 + 180379 = 180382
11 + 180371 = 180382
71 + 180311 = 180382
101 + 180281 = 180382
149 + 180233 = 180382
311 + 180071 = 180382
359 + 180023 = 180382
383 + 179999 = 180382

Showing the first eight; more decompositions exist.
