Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1396, here are decompositions:
- 23 + 1373 = 1396
- 29 + 1367 = 1396
- 89 + 1307 = 1396
- 107 + 1289 = 1396
- 113 + 1283 = 1396
- 137 + 1259 = 1396
- 167 + 1229 = 1396
- 173 + 1223 = 1396
Showing the first eight; more decompositions exist.
