Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86670, here are decompositions:
- 41 + 86629 = 86670
- 43 + 86627 = 86670
- 71 + 86599 = 86670
- 83 + 86587 = 86670
- 97 + 86573 = 86670
- 109 + 86561 = 86670
- 131 + 86539 = 86670
- 137 + 86533 = 86670
Showing the first eight; more decompositions exist.
