Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2318, here are decompositions:

7 + 2311 = 2318
31 + 2287 = 2318
37 + 2281 = 2318
67 + 2251 = 2318
79 + 2239 = 2318
97 + 2221 = 2318
139 + 2179 = 2318
157 + 2161 = 2318

Showing the first eight; more decompositions exist.
