Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425670, here are decompositions:
- 7 + 2147425663 = 2147425670
- 79 + 2147425591 = 2147425670
- 139 + 2147425531 = 2147425670
- 151 + 2147425519 = 2147425670
- 157 + 2147425513 = 2147425670
- 163 + 2147425507 = 2147425670
- 223 + 2147425447 = 2147425670
- 277 + 2147425393 = 2147425670
Showing the first eight; more decompositions exist.
