Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115600, here are decompositions:

3 + 115597 = 115600
11 + 115589 = 115600
29 + 115571 = 115600
47 + 115553 = 115600
53 + 115547 = 115600
101 + 115499 = 115600
131 + 115469 = 115600
179 + 115421 = 115600

Showing the first eight; more decompositions exist.
