Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72882, here are decompositions:

11 + 72871 = 72882
13 + 72869 = 72882
23 + 72859 = 72882
59 + 72823 = 72882
149 + 72733 = 72882
163 + 72719 = 72882
181 + 72701 = 72882
193 + 72689 = 72882

Showing the first eight; more decompositions exist.
