Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13586, here are decompositions:
- 19 + 13567 = 13586
- 73 + 13513 = 13586
- 109 + 13477 = 13586
- 277 + 13309 = 13586
- 337 + 13249 = 13586
- 367 + 13219 = 13586
- 409 + 13177 = 13586
- 439 + 13147 = 13586
Showing the first eight; more decompositions exist.
