Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425604, here are decompositions:
- 13 + 2147425591 = 2147425604
- 73 + 2147425531 = 2147425604
- 97 + 2147425507 = 2147425604
- 151 + 2147425453 = 2147425604
- 157 + 2147425447 = 2147425604
- 193 + 2147425411 = 2147425604
- 211 + 2147425393 = 2147425604
- 223 + 2147425381 = 2147425604
Showing the first eight; more decompositions exist.
