Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2276, here are decompositions:
- 3 + 2273 = 2276
- 7 + 2269 = 2276
- 37 + 2239 = 2276
- 73 + 2203 = 2276
- 97 + 2179 = 2276
- 139 + 2137 = 2276
- 163 + 2113 = 2276
- 193 + 2083 = 2276
Showing the first eight; more decompositions exist.
