Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2386, here are decompositions:
- 3 + 2383 = 2386
- 5 + 2381 = 2386
- 29 + 2357 = 2386
- 47 + 2339 = 2386
- 53 + 2333 = 2386
- 89 + 2297 = 2386
- 113 + 2273 = 2386
- 149 + 2237 = 2386
Showing the first eight; more decompositions exist.
