Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129994, here are decompositions:
- 23 + 129971 = 129994
- 41 + 129953 = 129994
- 101 + 129893 = 129994
- 107 + 129887 = 129994
- 191 + 129803 = 129994
- 257 + 129737 = 129994
- 353 + 129641 = 129994
- 401 + 129593 = 129994
Showing the first eight; more decompositions exist.
