Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425042, here are decompositions:
- 41 + 2147425001 = 2147425042
- 149 + 2147424893 = 2147425042
- 173 + 2147424869 = 2147425042
- 179 + 2147424863 = 2147425042
- 233 + 2147424809 = 2147425042
- 401 + 2147424641 = 2147425042
- 479 + 2147424563 = 2147425042
- 491 + 2147424551 = 2147425042
Showing the first eight; more decompositions exist.
