Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487892, here are decompositions:
- 23 + 2147487869 = 2147487892
- 59 + 2147487833 = 2147487892
- 89 + 2147487803 = 2147487892
- 113 + 2147487779 = 2147487892
- 191 + 2147487701 = 2147487892
- 269 + 2147487623 = 2147487892
- 281 + 2147487611 = 2147487892
- 293 + 2147487599 = 2147487892
Showing the first eight; more decompositions exist.
