Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10686, here are decompositions:
- 19 + 10667 = 10686
- 23 + 10663 = 10686
- 29 + 10657 = 10686
- 47 + 10639 = 10686
- 59 + 10627 = 10686
- 73 + 10613 = 10686
- 79 + 10607 = 10686
- 89 + 10597 = 10686
Showing the first eight; more decompositions exist.
