Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115782, here are decompositions:

5 + 115777 = 115782
11 + 115771 = 115782
13 + 115769 = 115782
19 + 115763 = 115782
31 + 115751 = 115782
41 + 115741 = 115782
89 + 115693 = 115782
103 + 115679 = 115782

Showing the first eight; more decompositions exist.
