Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129952, here are decompositions:
- 59 + 129893 = 129952
- 149 + 129803 = 129952
- 233 + 129719 = 129952
- 281 + 129671 = 129952
- 311 + 129641 = 129952
- 359 + 129593 = 129952
- 419 + 129533 = 129952
- 443 + 129509 = 129952
Showing the first eight; more decompositions exist.
