Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425988, here are decompositions:
- 109 + 2147425879 = 2147425988
- 229 + 2147425759 = 2147425988
- 277 + 2147425711 = 2147425988
- 307 + 2147425681 = 2147425988
- 397 + 2147425591 = 2147425988
- 457 + 2147425531 = 2147425988
- 541 + 2147425447 = 2147425988
- 577 + 2147425411 = 2147425988
Showing the first eight; more decompositions exist.
