Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133372, here are decompositions:
- 23 + 133349 = 133372
- 53 + 133319 = 133372
- 89 + 133283 = 133372
- 101 + 133271 = 133372
- 131 + 133241 = 133372
- 251 + 133121 = 133372
- 263 + 133109 = 133372
- 269 + 133103 = 133372
Showing the first eight; more decompositions exist.
