Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2282, here are decompositions:

13 + 2269 = 2282
31 + 2251 = 2282
43 + 2239 = 2282
61 + 2221 = 2282
79 + 2203 = 2282
103 + 2179 = 2282
139 + 2143 = 2282
151 + 2131 = 2282

Showing the first eight; more decompositions exist.
