Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2426, here are decompositions:
- 3 + 2423 = 2426
- 37 + 2389 = 2426
- 43 + 2383 = 2426
- 79 + 2347 = 2426
- 139 + 2287 = 2426
- 157 + 2269 = 2426
- 223 + 2203 = 2426
- 283 + 2143 = 2426
Showing the first eight; more decompositions exist.
