Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115998, here are decompositions:

11 + 115987 = 115998
17 + 115981 = 115998
19 + 115979 = 115998
67 + 115931 = 115998
97 + 115901 = 115998
107 + 115891 = 115998
137 + 115861 = 115998
139 + 115859 = 115998

Showing the first eight; more decompositions exist.
