Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7882, here are decompositions:

3 + 7879 = 7882
5 + 7877 = 7882
29 + 7853 = 7882
41 + 7841 = 7882
53 + 7829 = 7882
59 + 7823 = 7882
89 + 7793 = 7882
179 + 7703 = 7882

Showing the first eight; more decompositions exist.
