Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115266, here are decompositions:

7 + 115259 = 115266
17 + 115249 = 115266
29 + 115237 = 115266
43 + 115223 = 115266
83 + 115183 = 115266
103 + 115163 = 115266
113 + 115153 = 115266
139 + 115127 = 115266

Showing the first eight; more decompositions exist.
