Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13290, here are decompositions:
- 23 + 13267 = 13290
- 31 + 13259 = 13290
- 41 + 13249 = 13290
- 61 + 13229 = 13290
- 71 + 13219 = 13290
- 73 + 13217 = 13290
- 103 + 13187 = 13290
- 107 + 13183 = 13290
Showing the first eight; more decompositions exist.
