Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425724, here are decompositions:
- 13 + 2147425711 = 2147425724
- 43 + 2147425681 = 2147425724
- 61 + 2147425663 = 2147425724
- 193 + 2147425531 = 2147425724
- 211 + 2147425513 = 2147425724
- 271 + 2147425453 = 2147425724
- 277 + 2147425447 = 2147425724
- 313 + 2147425411 = 2147425724
Showing the first eight; more decompositions exist.
