Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425848, here are decompositions:
- 89 + 2147425759 = 2147425848
- 137 + 2147425711 = 2147425848
- 167 + 2147425681 = 2147425848
- 241 + 2147425607 = 2147425848
- 257 + 2147425591 = 2147425848
- 307 + 2147425541 = 2147425848
- 317 + 2147425531 = 2147425848
- 401 + 2147425447 = 2147425848
Showing the first eight; more decompositions exist.
