Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2250, here are decompositions:

7 + 2243 = 2250
11 + 2239 = 2250
13 + 2237 = 2250
29 + 2221 = 2250
37 + 2213 = 2250
43 + 2207 = 2250
47 + 2203 = 2250
71 + 2179 = 2250

Showing the first eight; more decompositions exist.
