Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147928, here are decompositions:
- 47 + 147881 = 147928
- 101 + 147827 = 147928
- 149 + 147779 = 147928
- 167 + 147761 = 147928
- 239 + 147689 = 147928
- 257 + 147671 = 147928
- 281 + 147647 = 147928
- 311 + 147617 = 147928
Showing the first eight; more decompositions exist.
