Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139552, here are decompositions:
- 5 + 139547 = 139552
- 41 + 139511 = 139552
- 59 + 139493 = 139552
- 113 + 139439 = 139552
- 191 + 139361 = 139552
- 239 + 139313 = 139552
- 251 + 139301 = 139552
- 311 + 139241 = 139552
Showing the first eight; more decompositions exist.
