Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139612, here are decompositions:
- 3 + 139609 = 139612
- 23 + 139589 = 139612
- 41 + 139571 = 139612
- 101 + 139511 = 139612
- 173 + 139439 = 139612
- 251 + 139361 = 139612
- 269 + 139343 = 139612
- 311 + 139301 = 139612
Showing the first eight; more decompositions exist.
