Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66382, here are decompositions:

5 + 66377 = 66382
23 + 66359 = 66382
89 + 66293 = 66382
191 + 66191 = 66382
293 + 66089 = 66382
311 + 66071 = 66382
353 + 66029 = 66382
389 + 65993 = 66382

Showing the first eight; more decompositions exist.
