Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129344, here are decompositions:
- 3 + 129341 = 129344
- 31 + 129313 = 129344
- 67 + 129277 = 129344
- 151 + 129193 = 129344
- 157 + 129187 = 129344
- 223 + 129121 = 129344
- 283 + 129061 = 129344
- 307 + 129037 = 129344
Showing the first eight; more decompositions exist.
