Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129846, here are decompositions:
- 5 + 129841 = 129846
- 43 + 129803 = 129846
- 53 + 129793 = 129846
- 83 + 129763 = 129846
- 89 + 129757 = 129846
- 97 + 129749 = 129846
- 109 + 129737 = 129846
- 113 + 129733 = 129846
Showing the first eight; more decompositions exist.
