Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475262, here are decompositions:
- 5 + 2147475257 = 2147475262
- 11 + 2147475251 = 2147475262
- 29 + 2147475233 = 2147475262
- 41 + 2147475221 = 2147475262
- 59 + 2147475203 = 2147475262
- 83 + 2147475179 = 2147475262
- 113 + 2147475149 = 2147475262
- 311 + 2147474951 = 2147475262
Showing the first eight; more decompositions exist.
