Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139706, here are decompositions:
- 3 + 139703 = 139706
- 43 + 139663 = 139706
- 79 + 139627 = 139706
- 97 + 139609 = 139706
- 109 + 139597 = 139706
- 223 + 139483 = 139706
- 277 + 139429 = 139706
- 283 + 139423 = 139706
Showing the first eight; more decompositions exist.
