Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425934, here are decompositions:
- 223 + 2147425711 = 2147425934
- 271 + 2147425663 = 2147425934
- 421 + 2147425513 = 2147425934
- 487 + 2147425447 = 2147425934
- 523 + 2147425411 = 2147425934
- 541 + 2147425393 = 2147425934
- 601 + 2147425333 = 2147425934
- 691 + 2147425243 = 2147425934
Showing the first eight; more decompositions exist.
