Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2300, here are decompositions:

3 + 2297 = 2300
7 + 2293 = 2300
13 + 2287 = 2300
19 + 2281 = 2300
31 + 2269 = 2300
61 + 2239 = 2300
79 + 2221 = 2300
97 + 2203 = 2300

Showing the first eight; more decompositions exist.
