Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425772, here are decompositions:
- 13 + 2147425759 = 2147425772
- 43 + 2147425729 = 2147425772
- 61 + 2147425711 = 2147425772
- 109 + 2147425663 = 2147425772
- 181 + 2147425591 = 2147425772
- 241 + 2147425531 = 2147425772
- 379 + 2147425393 = 2147425772
- 439 + 2147425333 = 2147425772
Showing the first eight; more decompositions exist.
