Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47372, here are decompositions:
- 19 + 47353 = 47372
- 79 + 47293 = 47372
- 103 + 47269 = 47372
- 151 + 47221 = 47372
- 211 + 47161 = 47372
- 223 + 47149 = 47372
- 229 + 47143 = 47372
- 313 + 47059 = 47372
Showing the first eight; more decompositions exist.
