Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139378, here are decompositions:
- 11 + 139367 = 139378
- 17 + 139361 = 139378
- 137 + 139241 = 139378
- 179 + 139199 = 139378
- 191 + 139187 = 139378
- 257 + 139121 = 139378
- 269 + 139109 = 139378
- 311 + 139067 = 139378
Showing the first eight; more decompositions exist.
