Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493008, here are decompositions:
- 7 + 2147493001 = 2147493008
- 79 + 2147492929 = 2147493008
- 307 + 2147492701 = 2147493008
- 337 + 2147492671 = 2147493008
- 457 + 2147492551 = 2147493008
- 487 + 2147492521 = 2147493008
- 691 + 2147492317 = 2147493008
- 709 + 2147492299 = 2147493008
Showing the first eight; more decompositions exist.
