Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1426, here are decompositions:
- 3 + 1423 = 1426
- 17 + 1409 = 1426
- 53 + 1373 = 1426
- 59 + 1367 = 1426
- 107 + 1319 = 1426
- 137 + 1289 = 1426
- 149 + 1277 = 1426
- 167 + 1259 = 1426
Showing the first eight; more decompositions exist.
