Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143372, here are decompositions:
- 43 + 143329 = 143372
- 109 + 143263 = 143372
- 379 + 142993 = 143372
- 409 + 142963 = 143372
- 433 + 142939 = 143372
- 499 + 142873 = 143372
- 601 + 142771 = 143372
- 613 + 142759 = 143372
Showing the first eight; more decompositions exist.
