Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13230, here are decompositions:
- 11 + 13219 = 13230
- 13 + 13217 = 13230
- 43 + 13187 = 13230
- 47 + 13183 = 13230
- 53 + 13177 = 13230
- 59 + 13171 = 13230
- 67 + 13163 = 13230
- 71 + 13159 = 13230
Showing the first eight; more decompositions exist.
