Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2312, here are decompositions:

3 + 2309 = 2312
19 + 2293 = 2312
31 + 2281 = 2312
43 + 2269 = 2312
61 + 2251 = 2312
73 + 2239 = 2312
109 + 2203 = 2312
151 + 2161 = 2312

Showing the first eight; more decompositions exist.
