Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2284, here are decompositions:
- 3 + 2281 = 2284
- 11 + 2273 = 2284
- 17 + 2267 = 2284
- 41 + 2243 = 2284
- 47 + 2237 = 2284
- 71 + 2213 = 2284
- 131 + 2153 = 2284
- 173 + 2111 = 2284
Showing the first eight; more decompositions exist.
