Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139372, here are decompositions:
- 3 + 139369 = 139372
- 5 + 139367 = 139372
- 11 + 139361 = 139372
- 29 + 139343 = 139372
- 59 + 139313 = 139372
- 71 + 139301 = 139372
- 131 + 139241 = 139372
- 173 + 139199 = 139372
Showing the first eight; more decompositions exist.
