Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425018, here are decompositions:
- 17 + 2147425001 = 2147425018
- 149 + 2147424869 = 2147425018
- 191 + 2147424827 = 2147425018
- 461 + 2147424557 = 2147425018
- 467 + 2147424551 = 2147425018
- 587 + 2147424431 = 2147425018
- 659 + 2147424359 = 2147425018
- 719 + 2147424299 = 2147425018
Showing the first eight; more decompositions exist.
