Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425748, here are decompositions:
- 19 + 2147425729 = 2147425748
- 37 + 2147425711 = 2147425748
- 67 + 2147425681 = 2147425748
- 157 + 2147425591 = 2147425748
- 229 + 2147425519 = 2147425748
- 241 + 2147425507 = 2147425748
- 337 + 2147425411 = 2147425748
- 367 + 2147425381 = 2147425748
Showing the first eight; more decompositions exist.
