Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147772, here are decompositions:
- 3 + 147769 = 147772
- 11 + 147761 = 147772
- 29 + 147743 = 147772
- 83 + 147689 = 147772
- 101 + 147671 = 147772
- 269 + 147503 = 147772
- 353 + 147419 = 147772
- 419 + 147353 = 147772
Showing the first eight; more decompositions exist.
