Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29686, here are decompositions:
- 3 + 29683 = 29686
- 17 + 29669 = 29686
- 23 + 29663 = 29686
- 53 + 29633 = 29686
- 113 + 29573 = 29686
- 149 + 29537 = 29686
- 233 + 29453 = 29686
- 257 + 29429 = 29686
Showing the first eight; more decompositions exist.
