Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13402, here are decompositions:
- 3 + 13399 = 13402
- 5 + 13397 = 13402
- 71 + 13331 = 13402
- 89 + 13313 = 13402
- 173 + 13229 = 13402
- 239 + 13163 = 13402
- 251 + 13151 = 13402
- 281 + 13121 = 13402
Showing the first eight; more decompositions exist.
