Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1346, here are decompositions:
- 19 + 1327 = 1346
- 43 + 1303 = 1346
- 67 + 1279 = 1346
- 97 + 1249 = 1346
- 109 + 1237 = 1346
- 193 + 1153 = 1346
- 223 + 1123 = 1346
- 229 + 1117 = 1346
Showing the first eight; more decompositions exist.
