Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140278, here are decompositions:
- 29 + 140249 = 140278
- 41 + 140237 = 140278
- 71 + 140207 = 140278
- 101 + 140177 = 140278
- 107 + 140171 = 140278
- 167 + 140111 = 140278
- 269 + 140009 = 140278
- 311 + 139967 = 140278
Showing the first eight; more decompositions exist.
