Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129274, here are decompositions:
- 11 + 129263 = 129274
- 53 + 129221 = 129274
- 191 + 129083 = 129274
- 251 + 129023 = 129274
- 263 + 129011 = 129274
- 281 + 128993 = 129274
- 293 + 128981 = 129274
- 401 + 128873 = 129274
Showing the first eight; more decompositions exist.
