Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129894, here are decompositions:
- 7 + 129887 = 129894
- 41 + 129853 = 129894
- 53 + 129841 = 129894
- 101 + 129793 = 129894
- 131 + 129763 = 129894
- 137 + 129757 = 129894
- 157 + 129737 = 129894
- 223 + 129671 = 129894
Showing the first eight; more decompositions exist.
