Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129382, here are decompositions:
- 3 + 129379 = 129382
- 41 + 129341 = 129382
- 89 + 129293 = 129382
- 101 + 129281 = 129382
- 173 + 129209 = 129382
- 263 + 129119 = 129382
- 269 + 129113 = 129382
- 293 + 129089 = 129382
Showing the first eight; more decompositions exist.
