Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1372, here are decompositions:
- 5 + 1367 = 1372
- 11 + 1361 = 1372
- 53 + 1319 = 1372
- 71 + 1301 = 1372
- 83 + 1289 = 1372
- 89 + 1283 = 1372
- 113 + 1259 = 1372
- 149 + 1223 = 1372
Showing the first eight; more decompositions exist.
