Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13430, here are decompositions:
- 13 + 13417 = 13430
- 19 + 13411 = 13430
- 31 + 13399 = 13430
- 103 + 13327 = 13430
- 139 + 13291 = 13430
- 163 + 13267 = 13430
- 181 + 13249 = 13430
- 211 + 13219 = 13430
Showing the first eight; more decompositions exist.
