Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475292, here are decompositions:
- 23 + 2147475269 = 2147475292
- 41 + 2147475251 = 2147475292
- 59 + 2147475233 = 2147475292
- 71 + 2147475221 = 2147475292
- 89 + 2147475203 = 2147475292
- 113 + 2147475179 = 2147475292
- 401 + 2147474891 = 2147475292
- 449 + 2147474843 = 2147475292
Showing the first eight; more decompositions exist.
