Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425890, here are decompositions:
- 11 + 2147425879 = 2147425890
- 19 + 2147425871 = 2147425890
- 37 + 2147425853 = 2147425890
- 131 + 2147425759 = 2147425890
- 179 + 2147425711 = 2147425890
- 227 + 2147425663 = 2147425890
- 283 + 2147425607 = 2147425890
- 331 + 2147425559 = 2147425890
Showing the first eight; more decompositions exist.
