Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129374, here are decompositions:
- 13 + 129361 = 129374
- 61 + 129313 = 129374
- 97 + 129277 = 129374
- 151 + 129223 = 129374
- 181 + 129193 = 129374
- 277 + 129097 = 129374
- 313 + 129061 = 129374
- 337 + 129037 = 129374
Showing the first eight; more decompositions exist.
