Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27882, here are decompositions:

31 + 27851 = 27882
59 + 27823 = 27882
73 + 27809 = 27882
79 + 27803 = 27882
83 + 27799 = 27882
89 + 27793 = 27882
103 + 27779 = 27882
109 + 27773 = 27882

Showing the first eight; more decompositions exist.
