Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147838, here are decompositions:
- 11 + 147827 = 147838
- 59 + 147779 = 147838
- 149 + 147689 = 147838
- 167 + 147671 = 147838
- 191 + 147647 = 147838
- 281 + 147557 = 147838
- 389 + 147449 = 147838
- 419 + 147419 = 147838
Showing the first eight; more decompositions exist.
