Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425342, here are decompositions:
- 59 + 2147425283 = 2147425342
- 173 + 2147425169 = 2147425342
- 239 + 2147425103 = 2147425342
- 269 + 2147425073 = 2147425342
- 443 + 2147424899 = 2147425342
- 449 + 2147424893 = 2147425342
- 479 + 2147424863 = 2147425342
- 701 + 2147424641 = 2147425342
Showing the first eight; more decompositions exist.
