Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475266, here are decompositions:
- 37 + 2147475229 = 2147475266
- 73 + 2147475193 = 2147475266
- 163 + 2147475103 = 2147475266
- 337 + 2147474929 = 2147475266
- 379 + 2147474887 = 2147475266
- 457 + 2147474809 = 2147475266
- 463 + 2147474803 = 2147475266
- 787 + 2147474479 = 2147475266
Showing the first eight; more decompositions exist.
