Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115116, here are decompositions:

17 + 115099 = 115116
37 + 115079 = 115116
59 + 115057 = 115116
97 + 115019 = 115116
103 + 115013 = 115116
149 + 114967 = 115116
227 + 114889 = 115116
233 + 114883 = 115116

Showing the first eight; more decompositions exist.
