Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47272, here are decompositions:
- 3 + 47269 = 47272
- 83 + 47189 = 47272
- 149 + 47123 = 47272
- 179 + 47093 = 47272
- 353 + 46919 = 47272
- 383 + 46889 = 47272
- 419 + 46853 = 47272
- 443 + 46829 = 47272
Showing the first eight; more decompositions exist.
