Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115986, here are decompositions:

5 + 115981 = 115986
7 + 115979 = 115986
23 + 115963 = 115986
53 + 115933 = 115986
83 + 115903 = 115986
103 + 115883 = 115986
107 + 115879 = 115986
109 + 115877 = 115986

Showing the first eight; more decompositions exist.
