Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139450, here are decompositions:
- 11 + 139439 = 139450
- 41 + 139409 = 139450
- 53 + 139397 = 139450
- 83 + 139367 = 139450
- 89 + 139361 = 139450
- 107 + 139343 = 139450
- 137 + 139313 = 139450
- 149 + 139301 = 139450
Showing the first eight; more decompositions exist.
