Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147712, here are decompositions:
- 3 + 147709 = 147712
- 23 + 147689 = 147712
- 41 + 147671 = 147712
- 83 + 147629 = 147712
- 263 + 147449 = 147712
- 293 + 147419 = 147712
- 311 + 147401 = 147712
- 359 + 147353 = 147712
Showing the first eight; more decompositions exist.
