Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47492, here are decompositions:
- 61 + 47431 = 47492
- 73 + 47419 = 47492
- 103 + 47389 = 47492
- 139 + 47353 = 47492
- 199 + 47293 = 47492
- 223 + 47269 = 47492
- 241 + 47251 = 47492
- 271 + 47221 = 47492
Showing the first eight; more decompositions exist.
