Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425842, here are decompositions:
- 83 + 2147425759 = 2147425842
- 113 + 2147425729 = 2147425842
- 131 + 2147425711 = 2147425842
- 179 + 2147425663 = 2147425842
- 251 + 2147425591 = 2147425842
- 283 + 2147425559 = 2147425842
- 311 + 2147425531 = 2147425842
- 389 + 2147425453 = 2147425842
Showing the first eight; more decompositions exist.
