Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147418946, here are decompositions:
- 149 + 2147418797 = 2147418946
- 227 + 2147418719 = 2147418946
- 263 + 2147418683 = 2147418946
- 269 + 2147418677 = 2147418946
- 293 + 2147418653 = 2147418946
- 317 + 2147418629 = 2147418946
- 347 + 2147418599 = 2147418946
- 443 + 2147418503 = 2147418946
Showing the first eight; more decompositions exist.
