Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147424, here are decompositions:
- 5 + 147419 = 147424
- 23 + 147401 = 147424
- 47 + 147377 = 147424
- 71 + 147353 = 147424
- 83 + 147341 = 147424
- 113 + 147311 = 147424
- 131 + 147293 = 147424
- 197 + 147227 = 147424
Showing the first eight; more decompositions exist.
