Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133438, here are decompositions:
- 47 + 133391 = 133438
- 59 + 133379 = 133438
- 89 + 133349 = 133438
- 101 + 133337 = 133438
- 167 + 133271 = 133438
- 197 + 133241 = 133438
- 251 + 133187 = 133438
- 269 + 133169 = 133438
Showing the first eight; more decompositions exist.
