Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1402, here are decompositions:
- 3 + 1399 = 1402
- 29 + 1373 = 1402
- 41 + 1361 = 1402
- 83 + 1319 = 1402
- 101 + 1301 = 1402
- 113 + 1289 = 1402
- 173 + 1229 = 1402
- 179 + 1223 = 1402
Showing the first eight; more decompositions exist.
