Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2342, here are decompositions:
- 3 + 2339 = 2342
- 31 + 2311 = 2342
- 61 + 2281 = 2342
- 73 + 2269 = 2342
- 103 + 2239 = 2342
- 139 + 2203 = 2342
- 163 + 2179 = 2342
- 181 + 2161 = 2342
Showing the first eight; more decompositions exist.
