Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8782, here are decompositions:

3 + 8779 = 8782
29 + 8753 = 8782
41 + 8741 = 8782
83 + 8699 = 8782
89 + 8693 = 8782
101 + 8681 = 8782
113 + 8669 = 8782
173 + 8609 = 8782

Showing the first eight; more decompositions exist.
